Welcome to the shape of jazz to come. He is pianist and singer-songwriter Jamie Cullum, currently one of a handful of “twentysomething” “jazz” artists interpreting pop songs old and new, and writing originals on his own unique terms. Cullum’s album Twentysomething, and his charismatic, energetic shows land him in the States as a bonafide UK superstar. Superstardom in the UK rarely assures success in the States (ask the Smiths and Robbie Williams about that), however, early stateside reviews of Cullum’s new album and his sensational stage show are pointing towards something new and interesting coming our way.
