Has anyone heard of The Answer? They're new, debut just came out on the 10th. I haven't really listened to them much, but they're like a mix of Foo Fighters and AC/DC (Zeppelin thrown in on the side). Pretty good stuff from what I've heard so far. They sound like a good candidate to carry the 70's Renaissance since Wolfmother broke-up.
