Photographer Alison Green has shot every Pitchfork festival since 2012 for the Reader, but this year she turned her camera away from the larger-than-life acts onstage and toward the everyday heroes who keep the festival running.

It’s easy to forget just how many people it takes to put on an event this size—including gate personnel, security guards, the workers who check IDs and hand out those coveted 21-and-over drink wristbands, the vendors at the Book Fort, the CHIRP Record Fair, and your favorite food tents, and of course the roadies and engineers who set up the gear and run the sound checks so you can hear Jamila Woods’s silky, honeyed vocals or Vince Staples’s dense wordplay in his distinctive Long Beach accent. They all play just as much a part in making the festival enjoyable as the artists themselves do.
