Jamie Cullum

At 33, English jazz-pop phenomenon Jamie Cullum's star is higher than ever. He's charismatic, has boundless energy on stage, and puts on wild live shows, never failing to give his all to the audience—which isn't always the case with multi-million-selling musicians. Rather than a truly progressive jazzman, Jamie is part of the tradition of British singer-songwriters that appeal equally to both young girls and their mothers. If you haven't had the opportunity to listen to his latest album Momentum, you can catch him instead live.
