Underground sensations like Shannon Shaw are anomalies these days. As the gale-force singer of Oakland trio Shannon and the Clams, her name has become synonymous with askew glamor and miscreant soulfulness: She and her misfit bandmates have spent nearly a decade sounding like the nails-tough Shangri-Las reborn and resembling hairsprayed-and-glittered John Waters movie extras, crying their eyes out and ready for a fight. (Waters has called them one of his favorite bands: "They're like my wet dream!" he once proclaimed.) The Clams mixed punk and girl groups with more conviction and maladjusted, leather-clad character than any other band of the late 2000s.
