1) Christina Perri‘s big break came when her unreleased song, the moody, angst-ridden “Jar of Hearts,” was featured on an episode of “So You Think You Can Dance” in 2010. It went on to sell more than 4 million copies in the U.S.—but it was no fluke. Since then, she’s released two full albums, 2011’s Lovestrong—featuring another multi-million selling single, “A Thousand Years”—and 2014’s Head or Heart. Perri is sharing billing on a summer tour with Colbie Caillat, who also made her breakthrough with a smash single—2007’s “Bubbly.” Caillat’s now promoting her fifth album, Gypsy Heart, and still pouring out melodic, catchy pop tunes. The first single off Gypsy Heart is the sweet, self-acceptance anthem “Try,” the video for which features the most shocking kind of nakedness—women without makeup. The Girls Night Out, Boys Can Come Too tour is at Stage AE, with special guest Rachel Platten. Doors open at 6 p.m. 400 North Shore Dr., North Shore. (HM)
2) Mat Kearney‘s 2014 single “Heartbeat” is an infectious dance-pop tune that’s likely to have the crowds at Hartwood Acres up out of their lawn chairs and dancing on the grass in seconds. The single, from Kearney’s fifth album, Just Kids, also features a remarkable video—shot in a single take from a drone over the (almost dry) Los Angeles riverbed. Originally from Eugene, Oregon, the Nashville-based musician’s music has appeared on television shows including “30 Rock,” “Friday Night Lights,” and “Grey’s Anatomy.” He appears at the Hartwood Acres free summer concert series with Americana-folk band Judah and the Lion, also from Nashville. 7.30 p.m. 200 Hartwood Acres, Hampton and Indiana townships.
