I would've paid $299 for a ticket that had Coldplay, Snow Patrol, and The Silversun Pickups playing.
Of Mice& Men are a really, really good band even though they haven't released anything out so far. If you like Emarosa try listening to Of Machines. They sound very similar to them. Hell, try listening to all the bands that played the Squash the Beef tour, all of them were amazing.
