Alright, look: I have no idea what this "mash up" is supposed to be. Apparently, members of Big Wheel Stunt Show, the Legend of Bigfoot and SweetKiss Momma (in addition to "more," evidently) will converge on the New Frontier stage and do ... something. Personally, I'm intrigued already. These are three (four? five?) bands that are mighty skilled at the rocking-the-pants-off game. It's no waste of a Friday to gather in a bar and hear three (four? five?) experienced bar bands rock some weekend into your head. The freewheeling nature of this show is an even bigger perk: members of some awesome bands getting together to create a brand new rock monster. You don't want to be there for something unrepeatable? You're crazy.
