At a show I attended at the Bottom Line in the '70's, there was a problem with the sound, and CB and the Magic Band had to stop playing. As the roadies were trying to straighten it out, someone in the crowd yelled, "Why don't you read some poetry!" Beefheart said, "What, poetry doesn't have to sound good?" He also played a mean harp. You never forget a Beefheart gig.
Lester Bangs' 1970 cover story in Rolling Stone from 1970 says it all.
Rest in Peace, brother.
