Battle of the Bands

Get ready to rock with the Ravens. But hurry. They may not be together much longer. Their drummer, Suki, is moving away. Unless...the Ravens can win the Battle of the Bands.

And this person is making them look really bad. But who is it? See if you can solve this rock-and-roll mystery.
