Tracy Bonham
Creative Director
A native of Eugene, Oregon, Tracy Bonham began singing at age 5, playing the violin at 9, and piano at age 14. After transferring to Berklee College of Music to study voice, leaving her full violin scholarship at the University of Southern California behind, she began to write songs on the guitar in 1994. She proved to be a quick study; Her 1996 major label debut, The Burdens of Being Upright (Island), went gold in the US as well as Holland, Australia, and Canada, spawning the hit single "Mother Mother". This lead to a pair of Grammy™ nominations in 1997, as well as an MTV Video Award nomination. She has since toured the world many times and has made television appearances on The Tonight Show with Jay Leno, Late Night with Conan O'Brien, Late Late Show with Craig Furgussen, as well as A & E's Breakfast for the Arts. Her third album "blink the brightest" was released on Rounder Records in 2005 and with that she placed many of the songs in major network TV shows such as Brothers and Sisters, The L Word, The Closer, What About Brian, and Army Wives. Tracy's vocals are featured on various artist's albums such as Aerosmith "Honkin On Bobo" (Columbia 2004), Wayfaring Strangers "This Train" (Rounder 2004), Ron Sexmith's "Whereabouts" (violin – 1999). In 2003 and 2006 she toured extensively with Blue Man Group singing and playing violin in major arenas as their featured guest performer and their opening act. Tracy is currently writing and recording her next album and teaching violin and voice in Brooklyn.

Matilda Marigolds
Instructor
Raised amidst the vibrant sounds and community of New York City, Matilda has been surrounded by music for as long as she can remember. The daughter of a drummer, she’d often attend her dad’s shows, falling asleep at the bar or backstage in the green room. It was almost inevitable that Matilda would soon start to blaze her own musical trails. She took her one (and only) drum lesson at five years old, joining her first band at the age of six. Matilda learned to play a slew of different instruments, including piano, bass, and guitar. She prides herself on being mostly self-taught, but took several years of classical piano lessons. That perspective would influence Matilda’s style of musical creation as she kicked off her solo career. In the summer of 2021, Matilda released her debut EP, Union. She unveiled some of the new music at a May performance at RWQuarantunes — one of the few emerging artists ever to be invited to perform on the platform. Matilda’s music can be found somewhere on the spectrum between Phoebe Bridgers, Fiona Apple, Patti Smith, PJ Harvey and Fleetwood Mac. She describes her nostalgic, genre-bending style as “a time capsule of not only all my feelings, but all of my musical influences.”
Dakota Lopez
Instructor
Surrounded by the bustling and artistically diverse streets of New York City, Dakota has always had an interest in music. At the age of 11, he began his lifelong journey to achieve mastership of the guitar. As time passed, his interests expanded into other instruments and the technology and thought process behind what pushes music to evoke emotion. As a result, he is currently enrolled in the sonic arts program at the City College of New York. Throughout his life, Dakota has worked with a multitude of gigging and recording projects, most notably Koi and Matter of Minutes. He has played various venues across the United States, most notably at the Okeechobee music festival where Matter of Minutes performed adjacent to legends including The Backseat Lovers and Tame Impala. He is very excited to share his experience with GMC students while learning from them the process!

Alex Kerkoff
Instructor
Hailing from the San Francisco Bay area, Alex started teaching himself guitar at the age of 13 and immediately fell in love with the instrument. His love for music lead to years of practicing which eventually brought him to USC’s Thornton School of Music. At the university level, Alex was able to augment and expand upon his rock and roll roots by becoming immersed in all styles and aspects of music - jazz, classical, flamenco, and country. Alex is passionate about and influenced by the sonic explorations of Jeff Beck, the restless creativity of Tom Waits and the dangerously funky rhythms of James Brown.
Eliza Densmore
Instructor
Eliza Densmore is a singer, songwriter, guitarist, and educator based in Brooklyn and originally from the Berkshires of Western Massachusetts. Eliza began writing songs on the piano as a teenager—inspired by singers like Norah Jones, Regina Spektor, and Billie Holiday. An interest in fingerstyle guitar and alternate tunings commenced after that, and soon Eliza went down the rabbit hole into the music of Nick Drake, Bon Iver, and Joni Mitchell on a journey that continues to this day. Eliza studied music at Colorado College and was recently a finalist in the renowned Kerrville Folk Festival’s songwriting competition. She’s released two albums of original music, has toured nationally, and is fluent in songwriting, music theory, intermediate piano and guitar, and ukulele. Folk Radio UK says of her most recent release: “Like a good photo, how you frame a subject makes all the difference and Edens provides a masterclass in composition." Eliza brings passion, patience, and humor to her students—tailoring lessons to students’ needs with a goal of instilling a life-long love of music

Jackson Fisher
Instructor
Born and raised in Brooklyn, Jackson Fisher was first introduced to music by his grandmother when he saw her watching a production of Wagner’s "Ring Cycle" as a child. He was immediately taken in by the dragons, giants, and extraordinary music. Later, Jackson picked up the guitar, telling his father that he would simply learn the song "Sultans of Swing" and then quit. Nearly a decade later, not only has he never quit, he is now a professional musician. Jackson went to Berklee College of Music, where he double-majored in performance and classical composition. He studied composition with Elena Lucas and jazz guitar with greats such as David Tronzo and Mike Stern, all while learning classical piano in his free time. While at Berklee, Jackson also began his teaching career, offering private lessons around Boston. During the summers he taught at home in Brooklyn, working with kids of all ages in private and group lessons. He was also employed by Berklee as a tutor, where he helped his fellow students with their studies in core music. Now that he's back in New York, Jackson is interested in pursuing further studies in classical composition and orchestration, learning bass, and playing and teaching music all over the NYC!
