edit: already listed by TOR, but so good it can be mentioned again :p
Orko
His last album as "LSG" the unreleased one, is one of my fav electronic albums of all time. I was so thankful when he gave it away for free on the net.
Incredible atmosphere, which felt like it could just keep morphing and expanding for ever. I'm always a little sad that it ends, because it just doesn't feel like it has to.
