There's not as much indie rock as I'd prefer, but Dawes on June 5 is a nice addition. And there's a bluegrass day! Bluegrass is perhaps the most underrated genre of music.
Of course, all the shows are free, so you can't go wrong. Here's the lineup so far courtesy of the PG, with additional acts to come:
June 1: The Wailers
June 2: Kathleen Edwards
June 3: The Pittsburgh Symphony Orchestra
June 5: Dawes
June 8: Carolina Chocolate Drops
June 9: Bluegrass Day with the Del McCoury Band, Peter Rowan Bluegrass Band and Greensky Bluegrass
June 10: Bruce Hornsby and the Noisemakers
In other unrelated news, I'm continuing to build up my new site Total Music Awards, which is currently focusing on the Billboard Music Awards. I've also started a site dedicated to Chicago camping, which could come in handy for those heading to Lollapalooza!
