He stands on his piano, plays, sings and dances at the same time: at his German concerts, Brit Jamie Cullum shows that you don't need a well-designed stage show for rousing jazz. This is how he convinces jazz and pop fans – and ignores narrow-minded critics. He has the soul and heart of a jazz musician, says Jamie Cullum. But he is also someone who makes pop music without apologizing for it. And he doesn't care about categories. Jazz or rock, he doesn't seem to be asking himself that question. On stage, he and his band usually get down to business so energetically that you actually have to be afraid for the piano, on whose keys he bangs, on which he sometimes even stands and sings, only to then spring down again and whirl like unleashed.
