KT Tunstall: Wilton's Music Hall, London ***

KATE TUNSTALL uses her initials for the same reason Joanne Rowling became JK — she thought a female name would generate preconceptions. Her music also errs on the side of neutrality: it's hard to get worked up by its pleasant strumminess. While preferable to Dido (the other British female songwriter who has won a huge audience by being the essence of normality), there are times during this "secret" gig when a burst of Winehousean nuttiness would have gone down a treat.
