Hot Rats (LP)
In the original sleeve notes for this LP, Frank's first after the original Mothers of Invention dissolved, Zappa desribes this largely instrumental album as "A movie for your ears". The Mothers' LPs featured a lot of musique concrete, satirical vocals and nippy editing techniques. Hot Rats is more into long jazzy solos, and multi-layered 16-track overdubbing which more or less opened the door to the progressive rock era. Only one track, Willie The Pimp, features vocals, from Captain Beefheart, no less.
