Don’t lie to yourself: Every red-blooded American can identify at least three songs by the Fray: “How to Save a Life,” “Over My Head,” and “You Found Me.” Their fourth album, Helios, was released in 2014, and it was pretty impressive. They’ve been darlings for 96.3 WDVD since 2005, so it’s no surprise the “Everything but the rap” radio station is sponsoring the show. They’ll be joined by American Authors, who gained a considerable amount of airtime with their insatiably catchy pop hit, “Best Day of My Life.”
