The sun is beaming down on Waxahatchee. Katie Crutchfield’s emotions-baring fuzz-rock project is about to head off on a string of U.K. tour dates with Tegan and Sara, on the strength of this year’s Essential album Cerulean Salt. And the new video for guitar-hammering noise-pop burst “Coast to Coast” — the one with the immortal line, “I’ll try to embrace the lows” — shows a sunny day on Alabama’s Waxahatchee Creek, the waterway that gave the band its name. Crutchfield frolics with her Grimes “Oblivion” cover partner (and former P.S. Eliot bandmate/twin sister) Allison Crutchfield of Swearin’, while previous Waxahatchee collaborator Ryan Russell directs. It’s direct and simple but tremendously effective, which suits the rough-hewn sing-along itself.
