Here's something from billboard.com:
Several veteran rock artists have teamed to record a track-by-track tribute to Pink Floyd's "The Wall." Due Sept. 27 via the Cleopatra Records' Purple Pyramid imprint, "Back Against the Wall" boasts the participation of Jethro Tull's Ian Anderson, the Doors' Robby Krieger and Yes' Rick Wakeman, Chris Squire and Steve Howe.
Another former Yes alum, Billy Sherwood, produced the tribute, which also features King Crimson's Adrian Belew and Tony Levin, ELP's Keith Emerson, Styx's Tommy Shaw and Toto's Steve Lukather, as well as actor Malcolm McDowell, who provides spoken dialogue.
Yet another great idea found in the chamber of the bong.
