BTBAM kicks some serious fucking ass. And if you aren't sold on them check out their cover album "The Anatomy Of..." covers of Metallica, Blind Melon, Queen, Pantera - they do it all and do it well. Early albums are a bit raw, but they've come a long way. It's too hard to describe, just give them a listen if you're willing to try a new band and you will not be disappoint. Not the kind of band you can skip songs on an album, they need to be listened to start to finish and easily take an hour of your time, but it's the best hour of the day.
One more for good measure.
