Last night pulled out 2 of his records I have not listened to in a long time. Zoot Allures and Apostrophe ('). Forgot how fun these 2 records are to listen to.
Below copied from amazon.
Zoot Allures is one of the most unique albums in Zappa's catalogue. Nearly all of the instruments are played by FZ himself (including bass!), with Ruth Underwood on percussion, the incomparable Terry Bozzio on drums, and some backing vocalists. It really is Zappa "stripped down" as its often described.
Again from a amazon review. Apostrophe.
Words can't really do the music justice, but if you could imagine blues and funk mixed with jazz and given a good stiff dose of sometimes brash irony, you'd begin to get an understanding.

Enjoy the music :-)
Have Fun
