The other reviews of this wonderful record concentrate on the songs which are indeed very good, with vulgar lyrics and great melodies which you will be humming for evermore.
However, there is so much more to enjoy as well. For starters, the album contains guitar playing up there with Zappa's best; Rat Tomago and The Sheik Yerbouti Tango are superb guitar solos and the magnificent twelve minutes that is Yo' Mama builds and soars to a massive climax, (sorry, there is no other way to describe it), accompanied by Tommy Mars only slightly overblown keyboards.
Some of the vocal and musical arrangements are stunning too. Apart from Yo' Mama, Bobby Brown, Dancin' Fool, Jewish Princess and the oft overlooked Wild Love are sooo good.
The band providing the basic live tracks was an excellent one, but almost all the songs benefit from having been heavily overdubbed, in the studio - a fact Zappa openly admits in the booklet notes.
Finally, even though City of Tiny Lights is my least favourite Zappa song, any album that has an impression of Bob Dylan moaning about his car not being fixed on time has got to deserve five stars.
