A Prairie Home Companion storyteller/host Garrison Keillor is the main attraction tonight, but it’s difficult to imagine his meandering tales of Lake Wobegon without his longtime pianist Richard Dworsky tinkling away behind him. Since 1986, the classically trained pianist has been Keillor’s regular accompanist not only on radio, but on multiple world tours and in the studio to boot. Along with Keillor, Dworsky has played with everyone from James Taylor to Yo-Yo Ma, and the beloved radio show would not be the same without his refined and whimsical touch behind the keys. Benaroya Hall, 200 University St., 215-4800, seattlesymphony.org/benaroya. 7:30 p.m. $29 and up. GE

ZZ Ward’s music has been setting the musical landscape on fire over the past year and a half. A potent mix of hip-hop, rock, R&B, and soul, guided by Ward’s simultaneously smoky and honey-smooth vocals, her debut album, ’Til the Casket Drops, is a damn fine listen. The Neptune. 7:30 p.m. $16.50 adv./$18 DOS. All ages. BP
