A new album by British rock legends Pink Floyd, their first in 20 years, is to be released on November 10, the group announced on Monday as billboards featuring the cover appeared around the world.
Named "The Endless River", the album features David Gilmour, Nick Mason and Richard Wright, and is based on a recording session by the three in 1993.
The album is a tribute to keyboardist Wright, who died in 2008, and was produced by Gilmour and Mason after they re-listened to the music from sessions when the band's last album "The Division Bell" was recorded.
The 18 tracks are mostly instrumental, the result of Gilmour and Mason "recording and upgrading the music, using the advantages of modern studio technology," according to the band's website.
The cover art, which features a man rowing a boat through clouds, is the work of an 18-year-old Egyptian digital artist Ahmed Emad Eldin and was unveiled on buildings from New York to Paris on Monday.
The album's final track is "Louder Than Words", with lyrics written by novelist Polly Samson, who is married to guitarist Gilmour.
