Darn: You pumping out some great albums lately! Wanted to comment on some of the previous ones in the alphabet already, but for some reason, I didn't. Brian Eno: A legend. And this album: Ambient phase 1! The story of how he came to create this album is also super nice. He travelled a lot, spend lots of time in airports and got so bored with the music played, he decide to create this album to be played at airports :) Some time ago, like 4 years ago my alter ego qsounds posted this one as well. In that post (here) you'll find a much slowed down version as well (time-lapsed), super interesting.
You missed listing the Chemical Brothers one in your list up in your post :)
