Joan Jett and the Blackhearts

Joan Jett's brand of attitude-laden bar rock got a boost a couple years back when Kristen Stewart played her in the Runaways biopic, and now the punk hero plays Marty Markowitz's free Seaside Summer Concert Series—for the second year running. Wanna holler along to "I Love Rock ’n' Roll" at Coney Island, beer ’n' coozie in hand? You got your wish.
