They're an indie metal/experimental band that my friend told me about recently. Check out their YouTube vids and that will give you the best idea of how crazy that effing drummer is, and how underground their shows are... like abandoned warehouses and what not. That's why I'm REALLY surprised they're featured on the new Bjork album. Anyway, check it out.
Yeah if you like Lightning Bolt, check out bands like Wolf Eyes and Liars. I love noise rock so much.
