Raised in Berkley, California, by a concert pianist mum and a music professor dad, Julian Pollack, better known as J3PO, was never likely to avoid music, it's practically written in his DNA. A virtuoso keyboard player since he was a kid (he was playing on NPR by the age of 18), he has released albums of his own ranging from straight jazz to complex sample-based jazztronica showing deep knowledge and love of analog synths and production techniques.

This combination of virtuoso playing and world-class studio nerdery has seen J3PO become a super in-demand sideman in the music scene. Collaborations so far read like a Who's Who of groove: Marcus Miller, Talib Kweli, Dave Sanborn, Eric Harland, Casey Benjamin, Michael League (Snarky Puppy), Kamasi Washington, The Lesson GK, Bob Reynolds, Tierney Sutton, John Pizzarelli, Louis Cato (The Tonight Show), Chris Bullock (Snarky Puppy), Grace Kelly, Ari Hoenig, Nir Felder, Chase Baird, Evan “EMAR” Marien, Grace Weber, and now...you.
