This album is where Zappa finally gets to show his personal style, segueing tracks together with blasts of noise and musique concrete, having reprises of songs, crazy vocals, it's all here.
The disc suffers from one of Zappa's wierder reissue choices, the placement of a single in the middle of this album. "Big LEg Emma" and "Why Doncha Do Me Right" jsut don't fit in with the album, and should have been bonus tracks included at the end, or better yet, on an album of single tracks otherwise unavailable. But instead, they are shoved in the middle of the cd, regardless of the effect that they have on the flow of the tracks.
Another problem, at least with the original Ryco issue, is that the remarkably dense Zappa art is impossible to see. If you have a chance to see the cover from the original vinyl, you will see far more detail that is easily presented on cd-size graphics. This is a shame, since Zappa himself didi the design work.
Nevertheless, this is an important, good album, and worth your time.
