If album covers are any signifier for a band’s sound, I delved into their discography expecting to hear sounds with a similarly unapologetic vividness. I was met with exactly this: brilliantly strong guitar riffs accompanied by stinging, fresh vocals in thoughtful arrangement. And when COIN’s four members stride confidently out onto a stage decorated solely with their band name and launch into opener “Growing Pains,” that brilliance is reflected out on the stage.
