I'd watch the DVD "Baby Snakes." Unfortunately, I never got to see Zappa, though "Freak Out" was one of the first real rock LP's I bought (The other two were "Are You Experienced" and "The Velvet Underground with Nico"). "Baby Snakes" gave me a dimension of Zappa I had never appreciated, which is the deep emotional engagement he has in his music and his phenomenal and generous connection with his audience. That said, I can still sing ("sing?" okay, maybe recite) along with "Freak Out" and "Absolutely Free," having remembered most of the lyrics. Many audiophiles believe "The Yellow Shark" is sonically excellent.
