Orphan Works 04-XX is like a series of stepping stones amid the broad lake of 36’s greater works. Actually, I have no idea what I’m talking about, especially when it comes to anything musical, but 36 normally charges for his music, and leaves it up to you whether to pay for this one.

Ambient music on Bandcamp is a dime-a-dozen, but there are some real wall-starers in here. Some aren’t. In all, highly recommended.
Similarly priced (at nothing, potentially), Music for Isolation is targeted at broke shelterers. The sentiment is reason enough to give it a listen, and it’s less than half an hour long.
