etai abramovich InstructoR
Born and raised in New York City, Etai Abramovich fell in love with music the first time he touched a drum set. Joining a rock band summer camp as a pianist in fourth grade, he surprised himself when he jumped eagerly at the opportunity to mount the drum throne. From that point on, he was glued to the seat, and his passion for all instruments blossomed. While at Beacon High School, he met the four boys who would quickly go on to become his besties and bandmates in LAUNDRY DAY. Nearly six years later, LAUNDRY DAY is still active as ever - signed to Warner Records and lauded by NME on the NME 100, their annual list of "essential new artists", in January 2020. Etai appreciates the immense power and magic that music educators possess. He feels honored to have the opportunity to pass the music onto the young students at GMC. After all, there is no greater joy than watching a child develop skill and passion, daydreaming about where it might take them later in life…
matilda margolis, 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.”
alex kerkhoff, 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.
sawyer nunes Instructor
Born in New Orleans, Sawyer began learning piano at the age of 4, and after a few months of practice felt the urge to learn just about every instrument he could get his hands on. Sawyer was drawn to music through his own curiosity - learning drums, guitar, bass, trumpet and clarinet within the next few years. All the while, Sawyer was training his voice and began to perform in choirs and musical theatre programs. After moving to NYC to perform in Matilda on Broadway at 12, he began to gravitate more towards writing, producing and releasing his own music. In high school, he made 4 best friends who shared his same passion for music and started the band LAUNDRY DAY. In the past few years, Sawyer has released 6 projects (including 4 of his own solo work), toured the U.S. and Europe opening and headlining festivals such as Govball and Austin City Limits. Sawyer has always had immense gratitude for the teachers who inspired his musical creativity and is excited to share the joy of music with all the students of GMC!
Chris callahan Instructor

After moving to NYC in 2013 to pursue an acting career Chris began hanging out at open mics, playing in bands and writing songs. Chris now fronts his band The Dudes as the primary songwriter and is working on recording their first EP due out this summer.
