We've gushed all over Olympia's Northern all-ages arts and music space more than is probably becoming. In all likelihood, it's starting to come off to those unacquainted with the venue's awesomeness as something of an unhealthy infatuation. But fuck it. We don't care. Screw the haters. Northern celebrates its two-year birthday Sunday with a piñata, cake, art by Jean Nagai and "singsongs and handclaps." It'll be a chance to celebrate the past two years and the future.

[Northern, 2-5 p.m., 321 Fourth Ave., Olympia, northernolympia.org]
