Rumer: Bloomsbury Theatre, London

RUMER'S PRISTINE VOICE — a dead ringer for Karen Carpenter's — is best suited to the kind of luxurious easy-listening treatment that sold millions of records in the Carpenters' glory days but is now as antiquated as the vinyl LP. Nonetheless, a major label has decided there's a gap in the market, and, surprisingly, they seem to be right: her first headlining show sold out the day tickets went on sale. "Nobody expected it," she told us. "It's incredible."
