Every math rock band, no wave band, avant-progressive band, etc owe a huge debt to Beefheart. Most punk bands -- many record labels. Even Sonic Youth were obviously inspired by Beefheart. Everyone from the Beatles to Henry cow, from The Residents to Sun City girls, from TFUL # 282 to the White Stripes. There was rock before Beefheart and rock after Beefheart, basically. He changed music the same way Godard changed cinema.
