It's like a full-scale ninja battle on stage: eight sweaty freaks brandishing guitars, horns, tambourines, microphones, pheromones, feedback and blood as they eviscerate everything that is decent and respectable about rock and roll. The band is Call Sign Cobra; that wet splat hitting your underpants is what's left of your spleen. With players culled from Scott Baio Army, Out on Bail, Mustangs and Madras, Rabbit Fight and Pariah Caste, Call Sign leaves no eardrum unscarred in its attempt to force-feed Rocket From the Crypt into Molly Hatchet -- and, of course, cement its position as the most blistering, organ-engorging live act in Denver.
