Josef Erich Zawinul (7 July 1932 – 11 September 2007) was an Austrian jazz keyboardist and composer. First coming to prominence with saxophonist Cannonball Adderley, Zawinul went on to play with Miles Davis and to become one of the creators of jazz fusion, a musical genre that combined jazz with rock. He co-founded the groups Weather Report and The Zawinul Syndicate. He pioneered the use of electric piano and synthesizer, and was named "Best Electric Keyboardist" twenty-eight times by the readers of Down Beat magazine.
