This indie rock act will spend this summer hitting lots of the big festivals including Bonnaroo, Lollapalooza, Firefly and Hangout, so tonight’s show serves as a warm-up date of sorts. You’ve probably heard songs such as “Shake, Shake, Shake,” which has been a big hit and even found its way into an ad for the Nissan Leaf. The song features soft vocals and uptempo music that suggests the band has caught on with fans of like-minded acts such as Mumford & Sons and Arcade Fire. Its latest single, “Further On,” is just as jubilant. (Niesel)
