Captain Beefheart performs at the Convocation hall, Toronto, 1974.

Avant-garde musician, Don Van Vliet, passed away on Friday. He was better known as Captain Beefheart, a stage name he adopted because of the "beef" he had in his heart, against society. He was a longtime friend and collaborator of Frank Zappa's. His breakthrough album, "Trout Mask Replica," came out in 1969 and was produced by Zappa. Click through for the song "Veteran's Day Poppys" off of the album, "Trout Mask Replica."

He stopped performing in the early 1980s to focus on his painting and sculpture, and did both, until he died of complications from multiple sclerosis at the age of 69.
