Kiefer is a pianist and producer on Stones Throw Records. He is also a frequent collaborator with others: a constant in Mndsgn's live trio, shared the stage with Moses Sumney and Terrance Martin, and lent production talents to the likes of Kaytranada and Anderson .Paak
He began playing piano as a child and producing beats at around age twelve, moving from San Diego to L.A. to study under renowned jazz guitarist Kenny Burrell at UCLA’s Jazz Studies program. There, he started thinking about the connection between the jazz piano he studied and the beats he created outside of school. While his peers were performing over live instrumentation, Kiefer produced electronic beats free from sampled melodies or drum breaks.
