For quite a long time, Akira Yamaoka and the Silent Hill game soundtracks have made more of an impression than most ambient music..That and older stuff like Coil, cold meat industry artists, death in june, etc etc..
I'm hesitant to mention that, though, because there's this retarded fan culture that's grown Not around silent hill but more the fucking evil nurses and pyramid head..
Seriously, ENOUGH WITH THE FUCKING EVIL NURSES AND PYRAMID HEADS YOU VAPID BASTARDS!
it's really good music, though. I thought the games were terrible, especially after 3 and 4..Even the 'good' games weren't that great actually. It was always about the soundtracks and the music..it isn't worth playing the games to hear the music, a lot of it only plays for a few seconds..
Okay, were're not sure if this thread is alive or asleep, but for anybody who'd ever read this and probably start / expand their adventure with ambient music we're obliged to recommend Gas for a more biological + dark + cleansing experience. It's a pity that we discovered him so late.
