Drone Zone on SomaFM (free internet radio) was how I discovered a lot of that stuff. Although they don't play the old classics as much these days, it's still good and they have a few similar stations there https://somafm.com/player24/station/dronezone
I generally find Deep Space One more appropriate for most of my coding, though I used Drone Zone a lot many years ago.
I've been supporting SomaFM for more than 20 years now, and am so grateful for it. Not just the ambient stuff, but Secret Agent and several others too.
I guess I agree (used to be a massive 90's EBM collector together with my ex, though I kind of got out of the loop of EBM end of 00's / start of 10's). Seeing a Woob album from 1994 recommended a few comments below <3 for CBL, I do like the track ~42 degrees.
How we used to find music: go to the record store every week to listen to whatever you couldn't afford, look at P2P networks at people who like similar music as you, and browse their collections. Eventually, use Discogs to search. Or simply talk with other people (at parties, on the internet) who also like the same music.
How we can find music nowadays: Spotify (and such). I mean, seriously. Their suggestions can open you up to a plethora of new artists. If you then look at the top 10, chances are you'll like some of their work. I found a lot of music this way, for all kind of genres. As Valve's Gabe used to say: piracy is a service problem. Though I am not sure Spotify is so good for the artists, given they earn pennies via that.
..and it is still nowhere to getting and downloading and listening 24/7 to every new release (or, well... trying to), using SMB to the NAS (which automatically gets the releases from a scene FTP) and Winamp locally to add some .m3u files.
I recommend Stair (2:22:22) by datassette for focus and ambient background. The artist recorded the sound of downtown Chicago overnight from his hotel and then processed and mixed this together with processed sounds from MS-DOS strategy game soundtracks from the 80s. Brilliant.
Not OP but I also often to listen to ambient while programming. A couple recommendations would be "Music for Nine Post Cards" and other works by Hiroshi Yoshimura, and "Music for 18 musicians" and others by Steve Reich.
In fact, the use of loops described in this article reminded me of what Reich called "phases", basically the same concept of emerging/shifting melodic patterns between different samples.
I'll second Max Richter's Sleep. Timeline by Edith Progue might interest you too. The later is my favorite xcalm down" CD even before Max Richter's, when I'm too restless to sleep.
And maybe Glitch (music) might be of interest as a starting point, especially the "Clicks & Cuts Series" which gave me a lot of pointers to interesting niche artists.
Biosphere - Shenzhou and Cirque, Stars of the Lid - The Tired Sounds of The Stars of the Lid are favorites of mine. I would also include everything by Microstoria which is not ambient but it works to the same end.
A good place for experimental music is ubu web, in fact Brian Eno is also over there[1].
Edit:
Also if you're a programmer and what to learn a new programming language, then check out SuperCollider[2]. You can use that to create your own ambient sounds. SC has a great library for creating user interfaces along with creating sound.
For a good intro the Sleepbot Environmental Broadcast radio is well worth listening to. Also their write up on how and why they produce the broadcast is really interesting.
A lot of great recs in this thread, but I'll a couple others I didn't see listed yet:
Mort Garson: Mother Earth's Plantasia
Hiroshi Yoshimura: Surround
Satoshi Ashikawa: Still Way (Wave Notation 2)
Shameless plug... Search BirdyMusic.com in Spotify/Apple Music/YouTube Music to hear some ambient music algo generated based on realtime Birdnet detections and weather in my backyard.
i have a 5hr playlist on spotify called lost in the sea of ambien which happens to have many of the artist recos here. title is a reference to haruomi hosono who said he got lost in the sea of ambient in the 80s after leaving ymo.
Yeah, everything's interconnected as Tangerine Dream got to work on GTA V soundtrack. There is this note about that track on Wikipedia:
The track "5:23" is included in the 2008 video game Grand Theft Auto IV and appears on the soundtrack album The Music of Grand Theft Auto IV. In the digital release it is listed as "Maiden Voyage". This track is very similar to, but does not credit, the song "Love on a Real Train" by Tangerine Dream from the Risky Business soundtrack. They had remixed the song for a then upcoming Tangerine Dream remix album but had their effort rejected so released it as 5'23 instead.
I've never really understood the appeal honestly. I feel it's more of a "masterpiece" in a historical sense, because it was an early electronic / ambient work which no one had really heard before and that gave it a huge cult following. Which is understandable, but outside of that, I don't see how it's any more interesting than basically any other ambient work of which I would say there is much much much better. Robin Guthrie comes to mind...
I don't see it a masterpiece in the same way I see Miles Davis' "Kind of Blue" is. The reason? Because I don't think there is a better Jazz album, ever, where as with Eno's early Ambient work, I think it was surpassed very quickly.
That said I'll give it another listen today and see if I can hear the magic.
