Keyboardist Bob James is a man who has worn many musical hats. He began as a progressive-jazz pianist in the early 1960s (he even recorded for famed underground avant-garde label ESP). By the '70s, however, he'd incorporated electric keyboards and become a star in the burgeoning fusion genre, making records which would later be sampled by countless hip-hop artists. Along the way, he was also involved in the soundtracks for everything from SERPICO to the TV show TAXI, and worked as arranger and producer for Dionne Warwick, Roberta Flack, and others. In the '90s, James became even more popular as a member of the smooth-jazz supergroup Fourplay.
