I was a Zappa fan until he started in on his jazz flavored musical albums. He lost me on this one. Zappa seemed to have become obsessed with jamming rather than writing music. Many of the albums which follow this one seem to  be nothing but recorded jams that seem to go on forever. Sales plummeted,  fans defected, I held onto my wallet and stopped buying Zappa albums. The  music became complex for its own sake-and less enjoyable. Some people loved  this Zappa material, it is true, but that group became smaller and smaller.  In retrospect, few critics (or fans) count Zappa's work after his first 3-4  albums as among his best.
