Merzbow. For some reason...
You need strong ears; it's not really music.
Well that's not quite true... it's music, just incompatible with the human mind.
It's very hard to describe why, but listening to it makes me feel good. Surely that makes no sense right? Well, apparently the guy is heavily into S&M. That quite accurately describes the experience of listening to his... tracks. Pain in audio form, driving you into submission until it turns into pleasure.
Some parts of it are quite moving and emotional. Again, I couldn't possibly explain why. I'm probably mad.
