It's raining more and more music from the clouds these days. I find interesting stuff on SoundCloud all the time, stuff uploaded by the artist or the record company, and of course tracks uploaded by people with a pretty loose attitude to copyright rules.
We'll let Maja Ratkje and Lasse Marhaug represent the artists, and Miasmah the record labels (listen to all of Kreng's fine new album).

If you are looking for some Robert Wyatt in the cloud, you will find tracks from official Wyatt albums as well as obscure cover songs. Check out "Alifib" by Cyann & Ben and Rokia Draore and Remi Dumoulin.
