This is a powerhouse show at the Siren’s Song that I can absolutely endorse. Oklahoma’s blast rockers Psychotic Reaction share the stage with a powerful lineup of Humboldt excellence. I’m talking about the charnel, country outhouse yowl of the Bow-legged Buzzards. And the stoney riff-ship Planet of Green, which, along with Thee Cokers, fills out a heavy sonic bid. 9 p.m. is the time, $5-$10 sliding scale, though nobody will be turned away for lack of funds.
