Billy Sherwood was the co-producer of several recent Yes albums, and in the case of "Open Your Eyes". He's also a musician and a composer. Before joining Yes, Billy was the leader of WORLD TRADE and made two records: "World Trade" (1989) and "Euphoria" (1995). In May 2000 he left the band. WORLD TRADE sounds like a world class band in every sense and has the ability to appeal to the listeners of Yes as well as those of other progressive rock bands.
