Win the original Damien Hirst painting created for The Hours' album cover

The spectacular and strange relationship between art and music is celebrated in a special issue of the Observer Music Monthly, starring Damien Hirst and The Hours on Sunday 19 April.

From John Lennon and Pete Townshend to MIA and Florence and The Machine, ex-art school students have been crucial to the history of British pop; and from Richard Hamilton and Peter Blake to Banksy, the number of artists who've collaborated with their favourite musicians is legion.

Now Damien Hirst, the most successful British artist of his generation, is working with his friends in the band The Hours: designing their record sleeves, art directing their videos and releasing their new album, See The Light, on his own specially-created label.

Go here to register to for the chance to win one of 20 signed litho prints of the Damien Hirst artwork created especially for The Hours new album sleeve. Then, on Sunday 19 April in Observer Music Monthly magazine we'll reveal what you have to do to enter the competition to win the original artwork – valued at £125,000 – created by Damien himself. Everyone who registers will also get the chance to exclusively download the track These Days from The Hours' new album See The Light.
