Pink Floyd's graphic designer Storm Thorgerson dies at 69 after battling with cancer. He is famous for designing the cover for Pink Floyd's "The Dark Side of the Moon" and creating many artworks for musicians including Led Zeppelin, Black Sabbath and Genesis in the past and the Cranberries and Anthrax more recently.

"The Dark Side of The Moon" was released in Britain in 1973 and became their first No.1 album in the United States. 

Thorgerson was a teenage friend of Pink Floyd's founding members and became their main designer. His most famous work is the prism and rainbow stripe on the "The Dark Side of the Moon", which marked its 40th anniversary last month.

Musicradar.com voted the cover the greatest album cover of all time in a poll last year. Another Pink Floyd's cover, "Animals" came 10th. Thorgerson main work was a pig flying over London's Battersea power station.

David Gilmour, guitarist and singer said: "He has been a constant force in my life, both at work and in private, a shoulder to cry on and a great friend."

"The artworks that he created for Pink Floyd from 1968 to the present day have been an inseparable part of our work."

Thorgerson's family said he died peacefully surrounded by family and friends on Thursday, April 18th. He will be greatly missed in the world of musicians.
