Jamie Cullum is an English pop and jazz-pop singer, songwriter, pianist, guitarist, and drummer. He is signed to a million-pound contract and his debut album has already registered double platinum in the UK. The "jazz" label doesn't hang that comfortably on the 24-year-old Cullum - he's more in the mould of polished lounge swingers and has more in common with artists like Billy Joel than any traditional jazz artist you might mention.
