Don’t you love alliteration? Anyway, local music blog Sound on the Sound is having a badass show tonight at the Blue Moon Tavern with What What Now, the Spinning Whips and Blessed Deep, which features members of Chuck Yay-Grr! and Lake of Falcons. And the super-secret headliner is a local band that we like (we’ve written about ’em before) who doesn’t plan shows very often in Seattle anymore. The show’s only $5, and it starts at 9 p.m. If you’re not in a position to drop the $15 on Go! Machine at the Croc or the $18.50 on Son Volt at Neumos, this show will be the fun times you’re looking for, but on the cheap.
