George Duke (January 12, 1946 – August 5, 2013) was an American musician, known as a keyboard pioneer, composer, singer and producer in both jazz and popular mainstream musical genres. He worked with numerous acclaimed artists as arranger, music director, writer and co-writer, record producer and as a professor of music. He first made a name for himself with the album The Jean-Luc Ponty Experience with the George Duke Trio. He was 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. He also taught a course on Jazz And American Culture at Merritt 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 Frank Zappa. Duke appeared on a number of Frank Zappa's albums through the 1970s. Duke served as a record producer and composer on two instrumental tracks on Miles Davis albums: "Backyard Ritual" (from Tutu, 1986) and "Cobra" (from Amandla, 1989). He has also worked with a number of notable Brazilian musicians, including singer Milton Nascimento, percussionist Airto Moreira and singer Flora Purim. Sheila E appeared on Duke's late-1970s solo albums Don't Let Go and Master of the Game. Duke was prominent in the R&B genre, releasing funk-based songs like "Reach for It" and "Dukey Stick". In 1979 he traveled to Rio de Janeiro, where he recorded the album A Brazilian Love Affair, on which he employed singers Flora Purim and Milton Nascimento and percussionist Airto Moreira. The album contained music in a wide assortment of genres, including some Latin jazz and jazz-influenced material. From a jazz standpoint, the album's most noteworthy songs include Nascimento's "Cravo e Canela," "Love Reborn," and "Up from the Sea It Arose and Ate Rio in One Swift Bite." The track "Brazilian Sugar" was featured on the 2006 video game Dead or Alive Xtreme 2. Meanwhile, Nascimento's vocal on the ballad "Ao Que Vai Nascer" is an example of Brazilian pop at its most sensuous. The 1992 film Leap of Faith featured gospel songs and choir produced by George Duke and choir master Edwin Hawkins.
