This is the Mothers of Invention's seventh album.  It, along with Weasals Ripped My Flesh, were compiled by Frank Zappa from old material recorded just before the original Mothers disbanded.  It is a combination of live and studio material.  The original Mothers are featured on some parts.  But other parts are more like  a Zappa solo album, featuring Ian Underwood, Sugar Cane Harris and Lowell George (who went on to form Little Feat).  Some of the material was taken from the same sessions as Zappa's first solo album, Hot Rats.  The CD is 41 minutes long, which is long by Zappa standards.  (Many of his albums were under 35 minutes).
