In 1966, long before the original Hairspray, black and white teens danced together to the bass overdrive and deep croak of Captain Beefheart and His Magic Band. Today blues lovers, avant-gardists and fans of dada, surrealism and abstract expressionism mourn and celebrate the Captain, aka Don Van Vliet. If you don’t believe people jitterbuged to “Diddy Wah Diddy,” watch the clip. And thanks to Jim Macnie for bringing it to my attention.
