Zappa?

Saw the band live on the Joe's Garage (1) tour. He played the whole album, then encored with Black Napkins.

Other great's that I enjoy are:
Apostrophe
One Size Fits All
OverNight Sensation

Bob

So, by group consensus, I guess you should buy them all. :-)

I'll start with Joe's Garage and One Size Fits All (seemingly the most enthuastic choices), and Yellow Shark (the classical influence seems interesting.

Peter mentions "Chungas Revenge", an album that seems to mark a transition of sorts (there were many), one of my favorites. The dirty wawa blues licks on "Road Ladies" stopped my buddy in his tracks when I played it for him. He was a Jimmie Page fanatic, but suddenly he took FZ seriously as a player, something he had not considered.
You might think about trying some earlier FZ first just to see where he was coming from. Whatever you do, dont forget his early stuff, even the silliest songs are great. Also anyone notice that "Burnt Weenie Sandwich" shows up on the "Filmore" and in "200 Motels" among other albums in various forms?

Guaranteed, if you buy enough Zappa, you'll be offended and/or disappointed, he was all over the place, from do-wop, fusion, classical, jazz and in between.
My favorite is Hot Rats, terrific fusion-y without much vocals.
2nd choice is where they put two of his albums on one cd - Overnite Sensation and One Size Fits All which is in his rock with humor style.
