Calvin Harris has played Coachella before. But this is his first headline appearance. It is also the first time a DJ has starred at the festival. It is not a surprising choice for Coachella organizers, however. In 2014, Harris reportedly attracted the second-largest crowd ever at the event. This year maybe he will break the record. It would not hurt if his girlfriend attends the festival. She happens to be America’s top earning performer, Taylor Swift. Harris and Swift just celebrated their first year anniversary last month. Coachella takes place in the desert town of Indio, California. It runs through April 24.
