Essential Zappa: what's missing from my collectio


I'm more interested in the instrumental side of Frank / Mothers. This is what I have so far:

The Yellow Shark: Personally, I think this is far and away
the best thing he ever did.
Waka Jawaka
Apostrophe / Overnight sensation
Civilization Phase 3
Hot Rats
Essential Zappa
Classical Zappa
Orchestral Favorites
Studio Tan
Guitar
Freak Out

It turns out I had more than I thought. Looking to fill in the holes in my collection. I took out "Lather" from the local library and thought it was ok. What about Chunga's Revenge (SP?)and Mothers Live (think it was a live concert recording from Austin, Tx.)?

I found a copy of "Burnt Weenie Sandwich" recently, and it is heavy on the instrumental. It's early, raw and quite good.
Don't recall exactly how instrumental:
Weasels Ripped My Flesh
Joe's Garage

I just do not get the Grand Wazoo, I recently bought it based on a Stereophile "To Die For rating" and just think it sounds 'noisy' after several listenings,

oh well, different strokes...
