I am the biggest Zappa fan....and this album is my favorite!....the sound quality is poor but the authenticity of the Fillmore sound shines thru.....this album features Flo & Eddie and both vocalist are in top form.....it's a comedy record, mixed with some awesome musicianship....the best track is "do you like my new car?"....I do not consider this a Mothers of Invention album since it has very little original mothers on it....it is a sonic trip thru groupies and touring.....purchase this CD and enjoy music the way they can't make now!!
