Hot Rats is instrumental except for the title cut. This means no lascivious sexual innuendo, no sarcastic comentary on the state of our plastic society, no random gurgles, shreiks, whines or whathaveyou; just music. The first song, Peaches en regalia, is probably one of Zappa's most famous ditty. My composition teacher hates the tune, but he's a piano player that doesn'r really get ornette coleman either. The title cut's vocal duties go to captain Beefheart, whose rhythmic gutteral utterances add to the groove more than tell a story.
The rest of the album is comprised of jazz rock tunes in the head-solos-head format. Both Peaches and Son of Mr Grene Genes are in the RealBook (and you don't wanna be stuck Sightreading Peaches..) so that's a reason for getting this album. My only qualm with this album is that some of the violin solos get a little boring when they reach their climax in the middle and drums hold that intensity till the end. More sensitive dynamics would have mad this (and sadly the majoriy of 70's fusion albums) a little easier on the attention span.
