Sad news: the man behind iconic designs for Pink Floyd, Mars Volta, and more has died.

Storm Thorgerson was a graphic designer and music video director whose work spanned over four decades. Born in Middlesex, he attended high school with Syd Barrett and Roger Waters, and would design many of Pink Floyd’s most famous album covers, including those for Dark Side of the Moon and Wish You Were Here. Thorgerson was a key member of the English art collective Hipgnosis until its dissolution in 1983.

Noted for his surrealist style, he would go on to design covers for some of the most notable names in rock music, including Led Zeppelin, Genesis, Peter Gabriel, and The Cult, along with contemporary acts like The Mars Volta and Muse. He also directed music videos for Pink Floyd and David Gilmour, among others.

The BBC reports that Thorgerson had been ill for some time with cancer. He was 69 years old.
