With all the bearded musicians making pretty music in this town—Fleet Foxes, Cave Singers, the Pica Beats—it's easy to forget that we built this city on rock and roll. Tonight's show will remind you. Wild Orchid Children play spastic jams laced with acidic vocals and psychedelic guitars. Navigator vs. Navigator remembered to take their ADD medication, but they've still got some spiraling-out-of-control, passionate moments. Finally, instrumental brethren Bronze Fawn and You.May.Die.in.the.Desert will be a nice warm-up to the crazy train. (Comet Tavern, 922 E Pike, 322-9272. 9 pm, $6.)
