Woodkid's soundtrack for Desierto has some incredible noise tracks, very reminiscent of SH1's ambient tracks. Highly recommend it for fans of Akira's earlier ambient work. I can't find any decent youtube links, but it is on Spotify. https://play.spotify.com/album/6fxJ3av95ygf59GVWy2ei9
As a reminder for other people, Session 9's soundtrack of course, since it has been an inspirational work for SH3.
