A vast majority of Americans think you should have to go through a background check to buy one of our too-ubiquitous guns, but thanks to legal loopholes, you really don’t. I-594 aims to fix those loopholes in Washington State, and a self-described “handful of comics, weirdos, and rockers”—like Brett Hamil, John Osebold, Emmett Montgomery, and local Misfits cover band Underworld Scum—gather tonight at Hollow Earth Radio to help raise requisite dollars. Solving problems through music and comedy? Yes, please. (Hollow Earth Radio, 2018 E Union St, brownpapertickets.com, 9 pm, $10 donation, all ages)
