VEISHEA is the largest student-run festival in the US. It's basically a weeklong showcase of Iowa State. I figured that the part you all would be specifically interested in is the big-name free concerts Friday and Saturday night:
Friday, April 20:
Saliva
Saturday, April 21:
Mike Jones
Chris Cagle
Story of the Year

If anything, it's the perfect chance to get f'ing hammered and enjoy free concerts, which is exactly what I will be doing.
