After short sets from Tom Morello, the Guitarmy (more on that later), the Bobby Sanabria band, and Das Racist, Dan Deacon popped up somewhere in the midst of the convergence, near the front. He then tried to coordinate the crowd in interpretive dance—something that surprisingly sort of worked, at least close to the stage. First, he asked the crowd to form a circle (impossible) and to lower to the knees. Then, gradually, people began to rise, jumping, shaking hands and fluttering fingers. For his second song, Deacon divided the park into two groups—each to follow the movements of a "captain" on either side. It was ambitious, and mostly confusing because of the sheer amount of bodies present, but experiencing Dan Deacon as a musical game of Simon Says at a rally full of thousands of people is most likely a situation that will never be replicated. You can check out the results I recorded below (though, many apologies for shaky iPhone footage).
