They really do rage, Some of the tempo changes they do are crazy. Very intense energy. Idiot crowd, though. I didn't let it ruin my show, but for every slow song the crowd murmur would rise, because I guess in their minds it's acceptable to talk during quieter songs, whatever. Still had a blast.
One of my favs. The hit Eau Claire at least once a year. I've also caught them in Menomonie, MSP, and Duluth. Unfortunetely I'll be in Orlando for work when they are in EC.
