Though not my favorite Zappa album, I must admit that I was pleasantly surprised with this 2012 release.  For the first time on CD is the COMPLETE Fillmore East recording.  Not the complete concert, but finally, Willie The Pimp Part Two is included.  The previous CD releases of Fillmore omitted Willie Part Two, which on the original vinyl was the fade-in opening track for side two. It's now back and even though it's only 1:54 in length, it really does make a difference.  And the sound is an improvement as well.
