I downloaded Zappa's Roxy & Elsewhere and Bongo Fury CDs. Roxy is in my top 10 CDs list, with it's insane avant-funk ramblings and experimental arrangements. Very good brass playing! Bongo is the perfect fusion of Zappa and Beefheart and sounds great despite the two's disliking towards each other during then. Worth it just for the insane guitar solo after Muffin Man.
