This is possibly Zappa's most bizarre, most satisfying release. We're Only In It... is much more coherent & tuneful, Hots Rats is more polished, & Uncle Meat is more indicative of Zappa's late-sixties approach, but Weasels... more comprehensively reflects the scope of Zappa's musical ambitions. Having said that, start with one of the albums that I have previously mentioned if you're new to FZ.
