Adrian Belew toured with Zappa in 1979, Talking Heads in 1980, then joined King Crimson in 1981. He's a great guitarist and a good singer but if he didn't have such good credentials Elephant Talk would fill me with rage.

PS for classical recommendations, I adore Stravinsky's "Rite of Spring." It's fairly modern and influential on 20th century experimental artists such as Zappa, so you would probably like it.
