Mike Silverman is a Las Vegas-based musician who has gone about as far as possible with the “one-man band” concept while still maintaining a strong touring presence and niche success. Under the stage name That 1 Guy, he has been taking his homemade musical doodads around the world for decades to perform a jammy style of art rock all his own. Tonight at 8 p.m. he returns to our county to cause a scene at Humbrews for those lucky enough to snag tickets to his unique live sonic concept act ($20, $18 advance).
