Amazon Prime is practically VH1 classic from a few years back without the 20 minutes of commercials per hour. Zappa at the Roxy was one i tried to watch recently. When I was 13, i thought the yellow snow was pretty edgy stuff. My favorite Zappa was with Flo and Eddie period, mainly their jam with John and Yoko on "Sometime in NYC".
Grown Zappa fans are a strange breed. I had an office mate who was a misogynist, who likened himself a jazz buff. He had little man's syndrome and a balding dome. He loved Zappa. He was a smart guy. A bit insecure to say the least.
I liken Zappa's music to a genius 13-year-old with no social-emotional skills. Brilliant stuff but not for an adult with emotional depth. "Dancing Fool" was inferior to "Disco Duck " in every way. Plus, He spawned Dweezil!
