British pianist/vocalist and songwriting Jamie Cullum mixes jazz with melodic pop and rock into a crossover style that brings to mind artists such as Harry Connick, Jr and Norah Jones. Cullum will just as often cover a swinging jazz standard as a modern rock song, and his original compositions move from earnest ballads to songs of sardonic wit. As a showman he's equal parts Ben Folds and Billy Joel and on his 2004 release Twentysomething. he won XPN listeners over with songs like his covers of Radiohead's "High And Dry," The Neptunes' "Frontin'," "The Wind Cries Mary" by Jimi Hendrix along with standards like "Singing In The Rain," and "I Could Have Danced All Night."
