We're co-sponsoring this one with Daytrotter and Pygmalion Music Festival, and it should be pretty epic.
Ra Ra Riot
(one, possible two acts TBA)
Festivities are at the Kalyx Center in Monticello, just about a half hour west of Champaign-Urbana (google map). 7 pm, no cover. Camping available, carpooling encouraged!
