I saw Black Stone Cherry open for Alter Bridge a few weeks ago. They stole the show, and a lot of that was because of John Fred's absolute monster playing. He has tremendous power and drive, and he's also a great showman (standing up while he plays, flipping sticks all over the place and so on). Definitely a guy to watch, and I recommend any hard rock fan go see Black Stone Cherry live if you get the chance. They put on a great rock & roll show.
Check out this solo (no points for identifying some of his biggest influences):
