This lovely lady ain't your normal singer/songwriter. The Grammy Award-winner's use of technology has proved to produce some truly astounding electronic music. Her latest album Sparks is said to be her most ambitious yet, and this is your only chance to see it performed live. She'll be joined by Leafcutter John. He's designed and created a system that creates unique music through the use of light, which is then performed by his 'creatures'. No, we have no idea how that's possible either, but it sounds damn good so don't miss out. Over 14s only, under 16s must be accompanied by an adult.
