The Mothers / Frank Zappa / Fillmore East - June 1971:  When they Play their instruments, they play as well as any group in history.  When they play Live, they are often silly, immature, and crude.  Many times when such concerts have been released as albums, they are embarrassing to the point of being unlistenable.  This album, however, even though it is as crude and as childish as ever, is more fun than you would expect.  Besides that, where else are you going to find "The Mud Shark"?  No, this is not an album for the kiddies.  Yes, it is kinda fun.  I like it (despite myself), so I give it four stars.
