At least one of the bands will have a female singer.
At least two of the bands will have basses with more than four strings.

During at least one of the bands, there will be a bottle of Jack Daniels, amongst the monitors on the front of the stage.
At least five of the bands will have members that you will have talked with around the bars or the signing tables and will be cool as hell.
At least three of the bands will have guitarists and drummers that will throw picks and drum sticks out to the crowd.
At least one of the bands will have a keyboardist that will throw a KORG keyboard out into the crowd.

And it will hit the one guy that has been an asshole all night and trying to start a mosh pit during a classical keyboard instrumental part. Ok that won't happen as it will be a legal/insurance nightmare for Glenn, that would PWN!!!
