Leilani Kilgore

Lauded by Guitar World for her “killer vibe and chops to back it up,” Leilani Kilgore is a bona fide rising star whose distinctive, blistering rock sound features elements of soulful blues and fearless, unapologetic emotional expression. The West Coast native first began playing professionally at the age of 14 before honing her skills with performance- and guitar-focused training at the renowned Berklee College of Music, and she has garnered critical acclaim throughout the industry for her prodigious musicianship and immense sonic profile ever since.

At Guitar Thrills, we’ve long believed progressive metal is where the guitar reaches its outer limits. It is not merely a genre but a proving ground, where technique collides with imagination, composition carries as much weight as execution, and guitarists are measured not only by speed, but by vision. To become a progressive metal guitarist is to step into one of the instrument’s most demanding disciplines, requiring obsessive precision, harmonic sophistication, rhythmic fluency, and an unrelenting commitment to evolution. The greatest players in the genre are not simply virtuosos—they are innovators.

Progressive metal is often reduced to clichés about odd meters, seven-string guitars, and impossible solos, but that only scratches the surface. From the Guitar Thrills perspective, progressive guitar playing has never been about complexity for complexity’s sake. It is about expanding what heavy music can express. Serious players study composition as deeply as they study technique, approach rhythm architecturally, and treat the guitar less as a riff machine than as an instrument for exploration. That mindset separates musicians from technicians and has defined the genre’s elite for decades.

Every generation has its architects. John Petrucci remains one of progressive metal’s foundational voices, helping define modern technical guitar through his work with Dream Theater. His precision, compositional ambition, and discipline created a blueprint countless players still follow. Then came boundary breakers like Tosin Abasi, whose revolutionary work with Animals as Leaders redefined extended-range guitar playing and introduced entirely new rhythmic and technical possibilities. Guthrie Govan brought astonishing improvisational fluency to the modern guitar conversation, while Plini showed progressive music could be cinematic, melodic, and emotionally expansive. Through Periphery, Misha Mansoor helped shape the sound of contemporary progressive heaviness. Together, these players did more than master the guitar—they changed its vocabulary.

For those aspiring to join their ranks, one truth becomes immediately clear: technique is only admission. Mastery begins after that. Becoming a progressive metal guitarist means developing rhythmic command far beyond conventional meter, elite technical mechanics, harmonic sophistication, compositional identity, and production awareness, all while cultivating an original artistic voice. It is a discipline built over years, not viral moments, and perhaps its greatest requirement is patience.

Among the modern players earning enormous respect in progressive circles, Nili Brosh stands apart as a compelling example of what progressive artistry can be today. From the Guitar Thrills perspective, Brosh represents something increasingly rare in modern virtuosity: balance. She brings together technique and taste, complexity and melody, fire and control in a way that has become central to her claim to fame. A graduate of Berklee College of Music, Brosh built her reputation not by chasing trends, but through uncompromising musicianship. Her solo recordings showcase advanced progressive vocabulary, fusion-level precision, and melodic writing that gives her work a distinct identity in a crowded instrumental landscape.

Her rise has also been shaped by world-class touring credentials, particularly her work with Danny Elfman, which brought her playing to major international audiences and demonstrated her versatility on some of the biggest stages. Yet among serious guitarists, her reputation rests on deeper qualities—touch, phrasing, articulation, and musical intelligence. Those are often the qualities casual listeners overlook but fellow musicians recognize immediately. At Guitar Thrills, we see those traits as what elevate a technically gifted guitarist into a true artistic voice, and they are a major reason Brosh is increasingly discussed among progressive guitar’s premier modern players.

One of progressive metal’s greatest strengths is that it refuses stagnation. It is always evolving. Today’s serious players blend jazz fusion, classical forms, ambient textures, electronic production, polyrhythmic experimentation, and extended-range innovations into constantly expanding musical language. The boundaries continue moving, and so does the standard. That can be intimidating for developing guitarists, but it is also inspiring, because progressive metal remains one of the few spaces where originality still carries as much weight as technical skill.

If the genre teaches one enduring lesson, it is that there is no final arrival—only deeper refinement. John Petrucci showed what discipline could build. Tosin Abasi showed what reinvention could unlock. Nili Brosh shows how precision and artistry can coexist at the highest level. For aspiring players, that may be the true path forward: not chasing complexity, not chasing speed, but chasing mastery. At Guitar Thrills, we believe that is where progressive metal has always lived—and where its future still waits.

INTERVIEW WITH NILI BOSH AND GUITAR THRILLS MAGAZINE

Leilani: Okay, there is so much to cover in this interview. I’m so excited to talk with you—thank you again. I thought we could start by going through your history a bit. First and foremost: moving from Israel to Boston at a young age is huge. Did you know early on that Berklee was where you wanted to attend school?

Nili: I think so. Growing up in Boston, and having a brother who also went to Berklee, I was familiar with that whole structure by early high school. Over my teenage years it became clear that it was the path for me.

Leilani: That’s so cool—your brother seems like he’s been a massive influence on you as a player and artist. I read that you started with classical—did you feel a connection to classical guitar, or was discovering bands like Extreme what really touched on your passion?

Nili: More the latter. Where I grew up, it was common for kids who were musically inclined and picking up guitar to start on a nylon-string instrument. It wasn’t that I was into classical guitar—it was more the belief that you start on nylon before you’re “seriously” considered, and your parents buy you an electric guitar. I get why that belief existed, but I don’t think that’s true. They’re two completely different instruments. Once I got into music that was heavily guitar-driven, that’s what made me want to pick up the instrument and practice for the sake of making music with guitar in it—rather than just taking lessons because your parents said you’re good at music.

Leilani: I totally get that. Nylon strings and that wider neck is completely different. So, when you convinced your parents and made the jump, what was your first electric guitar?

Nili: We had just moved to the Boston area, and my parents took me to Guitar Center with a price range in mind. I ended up with a low-end Fender—Mexican-made. It wasn’t a Squier. It wasn’t a bad instrument: it had a nice neck and stayed in tune well. For an entry-level guitar, it was a good choice at the time.

Leilani: When did you start playing Ibanez?

Nili: I became an Ibanez artist in 2011 when I started playing with Tony MacAlpine. But I was always an Ibanez fan—my favorite players played Ibanez guitars, and there was a theme there whether I fully understood it. It just made sense to me, and I always liked the vibe and what those guitars are about. For me it was kind of like a blessing—I didn’t think it would happen.

Leilani: Congratulations—especially on the signature guitar. That’s so cool. I was checking out your signature model—the yellow EMG pickups are sick, and the “Exclamation Point” neck inlays. From an aesthetic standpoint, why that color combination? It’s so striking.

Nili: Thank you. I wanted it to feel like the “midnight RG”—a retro-modern take on what RGs is to me. Something that reflects what I grew up with and what that would look like today. A combination of variables ended up landing there.

Leilani: It really does feel like a time capsule of the Ibanez RG spectrum. It’s killer. You must’ve been over the moon to work on that.

Nili: Yeah—that’s crazy. It was meant to capture what people think about when they think “RG.” That’s my best educated guess as to what that looks like.

Leilani: So Extreme discovering them at 12 is early, especially for that complex and technical style. Was there a particular album or song that set you on that trajectory?

Nili: Pornograffitti is my favorite album, and I got into it through “More Than Words,” like a lot of people. I loved the other singles too— “Hole Hearted,” etc. My brother kept telling me, “No—you must listen to the whole album. There’s more to it than you think, and it’s completely different, but it’s amazing.” Then I heard the full Nuno funky-metal thing, and I was hooked. It had so many of my favorite elements, and I’d never heard anything like it. I just thought: This is what I want to play on electric guitar. I want to make those sounds. That’s what started it for me.

Leilani: Totally understandable. What about that style attracts you as a form of expression?

Nili: It’s the combination: heavy guitars with funky riffs, and tonalities that come from older, blues-based playing—Van Halen and previous generations—kind of culminating there. That whole mix caught my ear, and I wanted to figure out how it came to be.

Leilani: You have a huge range of playing styles. Outside your typical lane, do you have a favorite direction you like to go?

Nili: I guess that stuff still has a big place in my heart. But on every album, I’ve made, I’ve always loved playing with different styles and keeping it versatile. That’s what keeps it fresh for me—going back and forth between different things. And that’s my life now, with the different gigs I do.

Leilani: Even listening through your records—there’s a broad palette. With Spectrum, for example, “Denitrification” feels like trance/heavy melodic shred, and then “Circus Wedding” feels like you’re in the middle of a Parisian soundtrack. Where does that range come from?

Nili: Honestly, I don’t know. I’ve heard so many kinds of music in my life—in different places I’ve traveled and studied—and I love it all. It’s just what I hear in my head. At first, it doesn’t seem like it all fits on one record, but I feel responsible for making what I hear in my head sound like it should. If it turns out to be two completely different styles, there’s still some running theme that makes it coherent on one record.

Leilani: What was your experience at Berklee?

Nili: I loved Berklee. I got to meet people from all over the world and be surrounded by influences from different places. I didn’t feel like I had the drive at the time to go searching for that stuff myself, so being embedded in that environment influenced me whether I wanted it to or not.

Leilani: I read you started teaching the summer seminars shortly after graduating—what was it like going from playing to instructing?

Nili: I did that for a few years. The weird part was that I was so young—only a couple years older than many of the students—so it was a little awkward to suddenly be “the teacher.” But breaking things down and explaining them felt good and natural.

Leilani: How was it working with Tony MacAlpine?

Nili: First gig out of college—very intimidating. I didn’t feel like I could hang, but he was very supportive and made me believe I could play that music with the rest of them. We had some wonderful years of touring together.

Leilani: You’ve done so many projects—from Dethklok to original music to touring—do you have a baseline “lifesaver” rig you go to?

Nili: I usually use Mesa/Boogie Triple Crowns. For travel gigs where I need something small, I use a Headrush MX5. That’s the emergency vehicle too—something you can put in a suitcase as a backup. These days there’s so much great gear that can pull you out of a bind. There’s a much bigger chance now that you can make whatever gear you’re handed work than there was 10–15 years ago.

Leilani: Your signature guitar has EMGs—was that influenced by Extreme and those kinds of players?

Nili: For the most part. I started playing EMGs when I was with Tony, especially playing a lot of 7-string at the time—that made sense. Then I moved away to passive EMGs, which a lot of people don’t realize is even a thing. But they make great passive pickups. My signature has the H1-A and S1s—humbucker and single-coil configuration. It’s a better fit for where I’m at and keeps it versatile for everything.

Leilani: About the upcoming album—are you continuing the stylistic diversity, or going in a different direction?

Nili: Kind of both. It still has a lot of different genres, but they feel like the next step in the journey—less repetition from previous records, but still stylistically diverse.

Leilani: What’s your songwriting process like?

Nili: Most of the time I hear a melody in my head—sometimes with arrangement ideas. I start by singing voice memos into my phone. If I hear additional arrangement stuff, I take notes, so I don’t forget it. Then when it’s time to flesh it out, I pull those voice memos up and sketch it out in Logic with fake instruments, to the best of my ability based on what I heard. Then I polish it from there.

Leilani: Are you touring the album?

Nili: I’m doing a short European tour to support the album, because Dethklok is going out right after for a couple months in North America. That’ll be a big block of touring for the first part of this year, and then additional things later.

Leilani: Is there a feature on your signature guitar you’re most proud of?

Nili: The culmination of everything. It’s meant to be versatile, because that’s what I do. It’s a testament to being able to do different gigs and styles with one instrument. The idea is that the guitar doesn’t get in your way—you’re using it as an ultimate tool.

Leilani: Do you feel different pressure on hired-gun gigs versus your original music?

Nili: Honestly, I’m hard on myself with whatever gig I do. It’s usually things no one else would care about and that don’t affect how you are as an employee. To me, a gig is a gig—I go into it with perfectionism regardless, so it doesn’t feel different.

Leilani: Any advice for people learning guitar or wanting to pursue that style?

Nili: Always lead with your ears. The instrument is secondary to using your ears. If you heard it first and then decided to play it, that’s usually the way to go. I don’t want to play something because it looks cool or feels good—I want it to be what I heard in my head, or what I think sounds good first. If you don’t like the way it sounds, then why play it? Music is listening—without that, what’s the point?

Leilani: What was it like being on Satriani’s G4 and Petrucci’s Guitar Universe?

Nili: Those are always great—another type of immersion. Great hangs, great students, opportunities for good guitar hangs. It’s an honor and a lot of fun.

Leilani: Did you think at Berklee you’d become such a fixed part of the guitar community?

Nili: No. I thought if I got a paying gig once in my career, I should consider myself lucky. That’s how we were taught—prepare to fall back on something else, and maybe if you’re lucky, someone will pay you one time.

Leilani: You’ve had amazing artists play on your albums—Andy Timmons, Stu Hamm. Is there a rhythm section you connect with most?

Nili: It’s a different connection with everyone, and that’s why I keep expanding the spectrum of rhythm section players I’ve worked with. There’s something with everyone. My current bandmates are especially special, and that’s why I brought a lot of them onto the new album.
