Ok - my time is up - I'm wrapping up the summary!
Be sure to check out @stationarytravels who has a bunch of new good posts related to ambient music. @floydkelley is often posting about ambient music - and a bit of Zen stuff which you might also enjoy. @headphonecommute is always pretty awesome.
Also - if you know @har - who sometimes goes by Ambient Guitarist and ran a long running darker ambient show on Stillstream for years... he's got a great new non-ambient more rock, prog, concept, soundscape, he's singing, he does amazing videos... album out that will blow you away.
And of course, my personal page: @johnkochnorthrup - I babble endlessly about everything, but mostly ambient music, jazz, robots, music, photographs, music, work, and ambient music.
