I'll put the disclaimer right up front: I was the Public Relations Director and blog editor at WIUX-FM 99.1 FM for years during my time at IU. In fact, it's a large part of what got me my current gig at NUVO and prepared me for my Sunday night shift at X103. In my (totally biased) opinion, student radio is one of the greatest professional preparations for a job in media, plus a total blast.
And the single best thing about my time at WIUX was definitely Culture Shock, the day-long, free outdoor music festival curated by the station and open to everyone. The Board of Directors at WIUX just announced this morning that this year's headliner is kid wonder Mac DeMarco, who will be touring brand new album Salad Days. A full lineup - generally around eight bands, including local, regional and national acts - will be announced in the coming days.
