Rock 'n' roll's afoot in Eureka and Arcata at 8 p.m. I used to call two simultaneous shows I wanted to see at different venues "slingshot shows," which made sense to me at the time. Anyway, slingshot your way across the bay and back to catch what you can of these two if you have the fortitude. Siren's Song has one-man band Kenny Bowling opening for FHOG — short for Finger Hash of the Gods — and the always exquisite Ultramafic (price TBA).

Up at the Outer Space, groove rock royalty Lord Ellis burns down the house in honor of its latest release Mouth of the Mad. Skate punk slack-engine Imperial Destructo opens ($5).
