I'm very much into metal, but I'm still very new to LSD, so I can't say I've listened to much under the lysergic mindstate yet (though I have attended a psychedelic/stoner/metal festival on 115ug and saw some great progressive metal. Also saw Buried At Sea on the comedown, which was one of the heaviest things I've seen so far). I have lots of experience with mushrooms, but contrast to LSD I need my music waaaaay calm on shrooms so I listen to a lot of (psychedelic) folk and singer songwriter stuff on it mostly. I'm guessing more technical/atmospheric or just plain euphoric metal would be great on LSD, as well as a lot of stoner rock/doom.
Thought I'd post some psychedelic-related metallic stuff, hopefully someone enjoys one or more of these
