Ambient favorites

I've always been an Eno fan, but in the past 2 years have really expanded my Ambient catalog. Some of my favorite artists:

Eno - he has a lot out - everything in his catalog is worth having and most is even better than "Music for Airports"

Harold Budd - like everything I have by him
Frip and Eno - especially "Evening Star"
Michael Brook
John Foxx
Robin Guthrie - not totally ambient - some is a little more lively.
Klaus Schulze - more electronic, but ambient
Tangerine Dream - really more electronic, less ambient

Also - some Jazz "ambient" I like a lot:

Tord Gustavsen Trio - all of their catalog
Bobo Stenson Trio - Cantando, War Orphans
Ralph Towner and Gay Burton - "Matchbook"

Here are some mixes I have on 8tracks.com:

Check out http://www.ambientmusicgude.com for more suggestions.

Check out the site "MixCloud". a TON of ambient there. See mixes by LowLight Mixes and also Chronaut. To add a little to Bdgregory's reply...give a listen to the "Mysterious Skin" movie soundtrack collaboration between Guthrie and Budd. Can be found on YouTube.

Others to try: Loscil, Helios, Jasper TX, & Tycho.

If you haven't heard them yet, you might enjoy STARS OF THE LID very much.

Brian Eno remains continues to be active in this area. Search him on YouTube and you are sure to find something more you will enjoy. Thursday Afternoon comes to mind.

thank you all for your thoughtful recommendations!
