Norah Jones is back. New haircut, new sound, new producer. The first of these, while very nice, needn't concern us too much. The second, meanwhile, is largely a result of the presence of the third, the ubiquitous Brian “Danger Mouse” Burton, who is working so hard these days I'm starting to suspect there might actually be two of him: Danger and Mouse.

He has been called “America’s sharpest musical storyteller” by Rolling Stone, and has enough talent to give Bob Dylan’s talking blues a run for their money. The East Nashville-based singer-songwriter, guitarist, yarn-spinner, troubadour and amiably agnostic stoner has 10 new stories on his 14^th album, the title of which acts as a pretty accurate calling card for the Snider experience: Agnostic Hymns and Stoner Fables.

Asked what attracted her to the music of South America, Catherine Ringer says, “C’est comme ça. Boom-ta-ta-boom, ta-ta-boom, ta-ta-boom-da boom, boom-da-da-boom.” She begins singing. “Boom-da-boom-da-boom, doo-doo-da-doo. It’s the rhythm of rock'n’roll,” she concludes. Ringer still exudes the spontaneity that defined Les Rita Mitsouko, whose first French hit, "Marcia Baïla", was fuelled by Latin rhythms. Yet now, she’s on her own, in London promoting her first solo album, Ring n’ Roll, released here this week. Her partner Fred Chichin died in November 2007.
