I am going to try and go cause TEN and MCS would be great headliners to see and there are a few smaller bands I would go see if I had time. Tonight Alive would be cool to see as well as TSSF, Anarbor, Go Radio (seen them a bunch but new album is my favorite of their work), and a few others. Never checked out Big D but may do so if I have time since people are really excited to see them.
Edit: Not normally a fan of ska but that song "Shining On" has to be one of the happiest songs I ever heard. I would love to hear that live.
