Though gates don't open until 3 p.m., the staff of the Walker Art Center and The Current have been busy setting up for hours already today. We kicked off a live broadcast from Rock the Garden at 1 p.m. and have already had guest appearances on-air by Doomtree's Dessa and P.O.S.

The weather forecast predicted rain today, but so far it's been hot and sunny here at the Walker's Sculpture Garden. We've got our fingers crossed that the weather cooperates this afternoon.

If you're following along at home, keep your radio tuned to 89.3 The Current -- coming up, we'll have interviews with more of the acts playing today in addition to live coverage of the performances themselves, starting with Howler at 3:45. And for now, check out these behind-the-scenes shots by MPR's Nate Ryan. We'll continue to add photos here throughout the day.
