If you have not yet heard this music, check it out - The Annunciation by Samuel Claiborne. It's solo acoustic improv piano - both meditative and reflective, can be listened to simply as background music, as well as listened to on a more intellectual level. Let me know what you think! You can buy it at CDBaby.com or on iTunes.
Tycho is good.......I like "boards of canada" or but lately a staple of mine has been the Omid (Hope) radio station on Pandora.com
