George M. Duke (January 12, 1946 – August 5, 2013) was an American keyboardist, composer, singer-songwriter and record producer. He worked with numerous 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, of which A Brazilian Love Affair from 1979 was his most popular, as well as for his collaborations with other musicians, particularly Frank Zappa.

George Duke was born in San Rafael, California and raised in Marin City. At four years old he became interested in the piano. His mother took him to see Duke Ellington in concert and told him about this experience. “I don’t remember it too well, but my mother told me I went crazy. I ran around saying ‘Get me a piano, get me a piano!'” He began his formal piano studies at the age of 7 at a local Baptist church.

He 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 of Music in 1967. He earned a master’s degree in composition from San Francisco State University in 1975.

Although Duke started playing classical music, he credited his cousin Charles Burrell for convincing him to switch to jazz. He explained that he “wanted to be free” and Burrell “more or less made the decision for me” by convincing him to “improvise and do what you want to do”. He taught a course on jazz and American culture at Merritt College in Oakland.

Duke recorded his first album in 1966. His second was with French violinist Jean-Luc Ponty, with whom he performed in San Francisco. After Frank Zappa and Cannonball Adderley heard him play, they invited him to join their bands. He spent two years with Zappa as a member of The Mothers of Invention, two years with Adderley, then returned to Zappa. Zappa played guitar solos on his album Feel (1974). He recorded I Love the Blues She Heard My Cry with Zappa’s bandmates Ruth Underwood, Tom Fowler, and Bruce Fowler and jazz guitarist Lee Ritenour.

In 1975, Duke fused jazz with pop, funk, and soul music on his album From Me to You. Three years later his album Reach for It entered the pop charts, and his audiences increased. During the 1980s his career moved to a second phase as he spent much of his time as a record producer. He produced pop and R&B hits for A Taste of Honey, Jeffrey Osborne, and Deniece Williams. His clients included Anita Baker, Rachelle Ferrell, Everette Harp, Gladys Knight, Melissa Manchester, Barry Manilow, The Pointer Sisters, Smokey Robinson, and Take 6.
