You can only take 5 albums to a deserted Island...

Sevs, maybe it doesn't hold up the best, but Demons and Wizards and Magician's Birthday still find their way into my rotation. Sweet Lorraine!

Is there weed on this desert island? If so:

Roxy Music's first (or second) 
Captain Beefhearts Brown Paper Wrapper
Grateful Deads Reckoning
King Crimsons Red
Wilco's live box set (because I spent so much money on it)

If only single malt scotch on this island... I suppose the list would be the same except I'd switch out Roxy Music with a T-Bone Burnett album, probably Truth Decay.

If none of the above is on the island (gasp), I'd have to take a lot more music so I wouldn't have to think about the fact that I was on a desert island.  

Boxer12, we should request that amp with tubes the size of a bottle to put together a distillery from fermented coconut milk ;-) 
Cannot find that amp though, i think i saw its photo in Hi-Fi+ once

Terry9.....I bet you'd love the soundtrack 1492 by Vangelus.  I have this on CD and declare it the best recorded record I have.  Not only is the sound wonderful, but the music is absolutely captivating.
