Nothing quite compares to watching a Mormon nicknamed “Chicken Bone George” stoke an audience of heathens into a pulsating frenzy … while the artist is mostly sitting down. The normally calculated and mild-mannered George Alan Sparhawk of Low fame screams distorted gospel commands when leading longtime side-project the Black-eyed Snakes. Meanwhile, “Big House” Bobby Olson’s guitar cranks out heavy-metal blues while the space is filled by the twin skins of drummer Brad Nelson and percussionist Bryan “Lefty” Johnson. The band’s third album — the first since 2003’s Rise Up! — is in the works.
