Frank Zappa And the Mothers Of Invention (1970)
Frank Zappa sort of smooshed all kinds of original influences into his sound from 1966 to 1970, and more or less never changed that style for the rest of his career (with a handful of exceptions). Well, one of those exceptions would have to go to this record, which typified the use of modern classical composition in rock music (mostly in the massively long suite “Little House I Used To Live In”). There’s also Zappa’s beloved doo-wop, some weird noise rock (which was also quite novel at the time) and all kinds of other things. While it’s recognizable as a Zappa record in some ways, it’s also a drastic change from Freak Out! and an evolution for Frank’s music. In that regard, it deserves inclusion on this list.
