I bought a cd by Air called Pocket Symphony (super-cool website) about 6 months ago or so. Never cracked it open until about a month ago.
Fantastic, much of it wonderfully ambient and a little evocative of a more rhythmically driven sort of Moon and the Melodies by Cocteau Twins and Harold Budd. Great stuff. There's one track that reminds me of gamelan, which I love. One of the songs is written by and features vocals of Jarvis Cocker, so the cool quotient is oober-high on this one.
Someone set the song Mer du Japon to this video of Tokyo trains to quite lovely effect, in my opinion. Enjoy!
