Thirty-seven years (!) after Dreamboat Annie introduced Heart as a new force in American hard rock, Ann and Nancy Wilson continue to win friends and influence people. Case in point: the 2012 Kennedy Center Honors, where honorees Led Zeppelin (along with the star- and president-packed audience) were serenaded by the Wilson sisters, who burned the fucking house down with a “Stairway to Heaven” rendition that left Robert Plant in tears. Tonight, Ann and Nancy Wilson will perform a rare acoustic set, after which they’ll have an onstage discussion with Charles R. Cross, who coauthored the sisters’ recent memoir, Kicking & Dreaming: A Story of Heart, Soul, and Rock & Roll. (Benaroya Hall, 200 University St, seattlesymphony.org, 7:30 pm, $70–$125)
