Blast beats are beyond overrated. I've seen musicians who won't take musicians unless they do blastbeats, and other people who only think a drummer is good if he does tons of blast beats. (I say "he" because obviously girls can't do it)
I think they are fine if done correctly, but I dunno if ANTR is the right place for them. They seemed forced in there. It didn't detract or anything, just seemed unnecessary.
