George Duke, jazz keyboardist, dies at 67 A representative says Grammy-winning jazz keyboardist and producer George Duke, whose sound infused acoustic jazz, electronic jazz, funk, R&B and soul, has died. He was 67. The representative said Duke died Monday night in Los Angeles. He was being treated for chronic lymphocytic leukemia. During his 40-year-plus career, Duke appeared on a number of Frank Zappa's albums and played in the Don Ellis Orchestra and Cannonball Adderley's band. He played keyboard on Michael Jackson's multiplatinum 1979 album, "Off the Wall," and was a producer for Miles Davis, Smokey Robinson, Gladys Knight, Dionne Warwick and Natalie Cole. He also released more than 30 solo albums. He released his final album, "DreamWeaver," on July 16, debuting at No. 1 on Billboard's contemporary jazz chart. "I think musicians are really the weavers of dreams," Duke said of the album in a recent video for Concord Records. That's why I wanted this album to be called 'DreamWeaver' because we start with nothing. The album starts with just a sound. And from that sound things begin to developed and nobody knows what's going to happen and then it ends up being a song...We're the weavers are dreams of ideas. Duke's wife, Corine, died from cancer last year.
