Billy Cowsill and Jeffrey Hatcher, core members of the Blue Shadows, seem like they’re worlds apart. A decade older than Hatcher, the U.S.-born Cowsill is a grizzled veteran of the music business who began his career singing in his family’s successful pop group, the Cowsills. Singer/guitarist Hatcher grew up in Winnipeg, and toiled in relative obscurity in the Vancouver music scene. But when the two men sing, a magical transformation takes place. Simple, direct songs that draw from country, folk R and B and rock influences, complement the pair’s instinctive vocal chemistry.
