Jamie Cullum first entered the music scene through jazz, but after a Grammy, two Golden Globe and three Brit Awards the star has made his stamp across a number of genres.
He is still widely known as the UK’s most successful jazz artist , having sold over 10 million albums worldwide after the release of his multi platinum Twentysomething LP.
He will return to a genre a little closer to his musical roots at BluesFest 2015, when he headlines the three-day event on Sunday, November 8.
The pianist and singer will draw on his extensive back catalogue, including his seventh studio album Interlude, and will be back by his usual band - plus a 12-piece big band.
BluesFest 2015 will also feature Tom Jones, Van Morisson and Dave Matthews Band.
Mr Cullum said: “Having performed at the very first BluesFest in 2011, it’s great to be asked back and I’m looking forward to performing on the same bill as all of (the other) incredible acts.”
This year’s event will also present a series of free daytime performances, making it one of London’s biggest’s free music festivals.
