Tonight, to celebrate the release of their new and lovely pop record Promenade, the eight-piece indie-folk band Grand Hallway will perform in the Fremont Abbey's gorgeous-sounding Great Hall with... wait for it... the 30-piece Seattle Rock Orchestra. It will be a lush flurry of percussion, trumpets, and strings, and they're even bringing in a small children's choir for some of the vocals, making the evening simultaneously beautiful, adorable, and stunning. (Fremont Abbey Arts Center, 4272 Fremont Ave N, www.fremontabbey.org. 7 pm, $8 adv/$10 DOS, all ages.)
