Suggest one obsure album we all should hear

Digital at Montreaux Album
Features Dizzy Gilespie, Toots Theilman and Benard "Pretty" Purdey. Live.
Also anything Frank Zappa.
What’s more obscure than a Mendocino beano or a Camarillo brillo? Not to mention a Jewish princess with a garlic aroma that could level Tacoma.
Zappa fans know what I’m talking about!
