Jeff Gitelman was born on February 5, 1982 in Soviet-ruled Moldavia. He and his family emigrated from Chișineu, Moldava in 1991 and moved to New Haven, Connecticut. His interest in music developed in his early childhood when he found a guitar in a trash can and his father fixed it for him. He subsequently learned how to speak English through listening to and learning how to play Western music, notably The Beatles.
Gitelman's music career began with musical performances when he was a teenager while attending Amity High School. After graduating high school, he attended Berklee College of Music in Boston, Massachusetts. His first professional job was recording and touring with Lauryn Hill which led him to tour as a guitarist with Alicia Keys, as well as perform with Stevie Wonder, David Bowie, and Chance the Rapper.
In 2010, Gitelman, along with Tim Walsh and Dan Edinberg formed The Stepkids, a psychedelic soul band. They released their debut self-titled album in 2011 under Stones Throw Records. The band toured and collaborated with Kimbra, Mayer Hawthorne, and Aloe Blacc.
Following his work with The Stepkids, Gitelman relocated to Los Angeles, California to focus on production. His guitar and production work is featured on J. Cole's 2014 Forest Hills Drive, Donnie Trumpet's Surf, Mac Miller's The Divine Feminine, ASAP Ferg's Always Strive and Prosper, as well as work with Dej Loaf and Kid Ink.
