Watermusic II by William Basinki is the perfect album for when you need to unwind or listen to something calming while you work. Basinki is an American avant garde composer, musician, sound artist, and video artist. He's best
known for his album The Disintegration Loops. Watermusic II is a little over an hour long, and is dreamy the whole way through. It helps me focus every time I listen to it.
