Putting aside the troll vocals and terrible underlying philosophies, some Black Metal has similarly lovely guitar soundwashes as well. It's an interesting paradox.
fascinating, I like all those artists but would've never tried sleeping to Metallica or Yngwie. I take it the fast tempos and high-energy don't keep you up?
I think there's some mechanical nature to the rhythms, and the chords tend to be complex enough that something is going on that keeps my subconscious occupied and makes it easier to lose awareness (and fall asleep).
Or maybe it's me. I fell asleep for a minute or two in a stadium while Rush was playing Time Stand Still as a college student (so age wasn't a factor ;) ).
wow! I think falling asleep during a Rush concert might be some new kind of cardinal sin - even if it's a relatively more mellow song :P
curious if more progressive metal works the same for you? (e.g. Dream Theater) rhythms are less regular, although kinda mathematical in some sense so I could see it still applying
