If you are a Frank Zappa fan and you don't have this CD you are really missing out.  This live recording shows how Frank was evolving away from the type of music the he made with Mothers Of Invention and moving more toward the style of music that introduced us to such classics as Apostrophe and Overnite Sensation. On this he teams up with George Duke on Keyboards, Napolean Murphy Brock on Sax and the talented Ruth Underwood on marimba and Percussion.  I saw Frank live a lot during this transitional period and I loved those shows.  They were so unpredictable.  You can hear that on this CD.  Cheapnis is amazing.
