Not just an ambitious and accomplished work in its own right, this 1973 prog stalwart also seems irresistible as a challenge to other artists.

Not content to simply cover Time or Brain Damage, last Christmas The Flaming Lipsreleased a recording of the entire album, roping in help from Henry Rollins and Peaches.

It’s also recently been painstakingly reproduced in 8-bit format, as reported previously on MusicRadar. Impressive level of dedication or a bedroom anorak with too much time on his hands? Who cares - it's bloody brilliant.

D is also for... Don’t Look Back: These ATP shows present artists performing an album from their back catalogue in its entirety. They may not be covers shows per se, but they’re still an excellent opportunity to hear live versions of lesser-played tracks. Forthcoming Don't Look Back shows include album playbacks from the likes of The Raincoats and Spiritualized.
