Don Van Vliet — the iconic experimental musician known as Captain Beefheart — died today due to complications from multiple sclerosis at a hospital in Northern California, according to reports. He was 69.
From 1967 through the early '80s, Van Vliet released some of the most challenging rock albums ever, which showed off his quirky knack for free-form experimental rhythms, avant-garde melodies, and his gruff, smoky howl. He released music that would challenge fans' assumptions and expectations about rock 'n' roll. "People like music to be in tune because they've heard it in tune all the time," Van Vliet said in 1978. "I really tried to break that down."
