KPFA's Robin Baxter interviews a slightly combative Frank Zappa in his hotel room. The two discuss Zappa's classical musical influences, and his own orchestral and choral compositions, as featured on his album and film, "200 Motels." Other topics touched upon in this brief interview include Zappa's then upcoming concert, shakeups in the Mothers of Invention, and what the public may or may not want to know about what goes on inside Frank's head. Insightful, informative, satirical, and always entertaining, this is classic Zappa from the early 1970s.
