Album: Dans Led Arbres, Canopée (ECM)

John Cage's centenary provides a perfect peg for a second album by this sound-as-music, music-as-sound improv quartet featuring Norwegian composer Christian Wallumrod on prepared piano and harmonium.

It's all very abstract (to the extent I thought one track was my fridge humming) but the sounds are generally so nice that they work well as a tasteful ambient accompaniment to domestic life. Listened to intently, however, it might make you mad.
