Every festival needs a new band like Chvrches: Breezy, accessible dance-poppers who know how to project. The second-from-last spot at this festival, which I’ve come to think of as the Cut Copy spot because of how great that band was in that place a few years ago, might now be the Chvrches spot. They’ve got a new album coming out, and it was exciting to hear new tracks “Clearest Blue,” “Leave A Trace,” and “Make Them Gold,” which already sound like they belong in the band’s set. But the best part of the set wasn’t hearing those songs. It was hearing the ones we already knew, sounding huge and anthemic as the sun set and the day’s oppressive heat finally lifted.
