album recs more than songs: the horror and the wild by the amazing devil (bandcamp, web site), flower of life by taleen kali (bandcamp, web site), and if you can find it, world of monsters by the drovers. (it came out in the 90s and if albums go out of print it probably has.)

i second the rec for russian doll! it's super weird - especially s2 - but natasha lyonne is fantastic.

my favorite background noise site is mynoise.net, which is full of soundscapes. some of them are more musical than others but there are a lot of them.
