Boris is awesome and everything they do is gold, but doom is just a slice of their repertoire. They work with Merzbow frequently, they play hardcore, dabble in shoegaze, and their latest album is ambient.
EDIT: and this is a wild hybrid of stoner rock and Visual Kei:
Oh, I know, their multifaceted output is what sets them apart. They got my attention a long time ago with that Nick Drake album cover spoof. I’ve seen them three times, once in the desert, where they attempted a daytime lightshow….
Another band in that realm, while not necessarily on point with with the thread topic but related, is Acid Mothers Temple, a sort of a modern Japanese Hawkwind. Not everything they’ve put out is great, but when they’re on, they get out there.
