The Ambient Jams mod adds hours of additional ambient music to the game, all original works improvised on the spot. (It's a jam!) Style is a mix of Tangerine Dream, Ambient Music, IDM, and a little bit of classical here and there. Most tracks are 15-20 mins+ for longer immersion. Current version has about 40 minutes of music, and the final is planned to be 2-3 hours.
Note: I've been getting reports of this mod crashing the game when loaded from the Steam Workshop, which I'm unable to reproduce on my end. If anyone has any idea what it could be, please let me know. Meanwhile, I have the mod temporarily stored on github if you want to install it directly into your mods folder.
