Deep in the city's concrete jungle, silence can echo for blocks. But listen closely. One voice pierces the hush. Andy Shadburne isn't content to sing lyrics; the Via Dove vocalist prefers to purr them instead, using his crushed-velvet delivery of rock & roll to rush the heartbeats of those listening. Shadburne roars with emotion and whimpers with longing, building heat with lingering, scratchy notes until he completely seduces his audience with husky vocal vibrations. And once Shadburne makes eye contact with his admirers, it's over; they're lost in the teasing growls of his tongue gymnastics.
