From the Wiki:
Belew toured with the Zappa band and appeared on Zappa’s 1979 album Sheik Yerbouti, most notably performing a Bob Dylan impersonation on the song “Flakes.” He also appeared in Zappa’s 1979 concert film, Baby Snakes. While with Zappa, Belew was mostly credited as rhythm guitarist, although he also played lead, melody, or noise lines, as well as singing lead on two songs (“Jones Crusher” and “City of Tiny Lites”). Belew has described his year in Zappa’s band as a “crash course” in music theory due to Zappa’s rigorous rehearsals and often technically demanding music, and has commented, “I went to the Frank Zappa School of Rock.”
Belew has also worked with David Bowie, Talking Heads, King Crimson, Tom Tom Club, Laurie Anderson, Tori Amos, Nine Inch Nails, among others and not to mention his solo work. Well, today is the dude’s birthday. Woot.
