Give me extreme, fast doom with clean vocals only (so no death/doom or black/doom, or even drone). Also looking for good Japanese rock bands, maybe like The Gazette, who I heard about from a friend.
Fast doom is an oxymoron tbh. Though I guess your best bet, if you haven't heard the name thrown around a bunch of times in every doom thread already, is Doomsword. I recommend their self-titled album.
