George Duke (born 12 January 1946 in San Rafael, California) is a multi-faceted American musician, known as a keyboard pioneer, composer, singer and producer in both jazz and popular mainstream musical genres. He has worked with numerous acclaimed artists as arranger, music director, writer and co-writer, record producer and professor of music. He first made a name for himself with the album The Jean-Luc Ponty Experience with the George Duke Trio. He is known primarily for thirty-odd solo albums as well as for his collaborations with other musicians, particularly Frank Zappa.

Duke attended Tamalpais High School in Mill Valley before earning a bachelor's degree in trombone and composition with a minor in contrabass, from the San Francisco Conservatory in 1967. Playing initially with friends from garages to local clubs, Duke quickly eased his way into session work, which refined his abilities and expanded his approach to music. (He later earned his Masters Degree in composition from San Francisco State University. His website mentions a short stint teaching a course on Jazz And American Culture at Merritt Junior College in Oakland). Beginning in 1967 Duke experimented further with jazz fusion, playing and recording with violinist Jean-Luc Ponty, as well as performing with the Don Ellis Orchestra, and Cannonball Adderley's band, while he acquainted himself with the avantgarde musician Frank Zappa. Duke appeared on a number of Frank Zappa's albums in the early and mid-1970s, including Chunga's Revenge, 200 Motels, Waka/Jawaka, The Grand Wazoo, Apostrophe, Over-Nite Sensation, One Size Fits All, Bongo Fury and Roxy & Elsewhere.
