It's crazy who you might run into at the Sundance Film Festival: Why look, there's head Jackass Johnny Knoxville, praising the daredevil escapes of Evel Knievel! And here comes Jack Black, pimping his cringe-comedy The D Train! And that guy in the beanie…whoa, is that Slash?
A number of big-name stars stopped by our Main Street headquarters, and luckily, we had a photographer on hand to capture the moment. Here are our best portraits of the actors, filmmakers and musicians who dropped by to hang out with us at Rolling Stone Live at the Merrell TrailScape.
