Part of the BBC Proms.
Who needs instruments when you have seven voices and seven bodies?The inimitable a cappella group Naturally 7 comes to the Proms fresh from performances at the O2 supporting Michael Buble. Building on the heritage of gospel with a style described as ?vocal play', the group performs its own original material as well as its inventive arrangements - including George Harrison's 'While My Guitar Gently Weeps' and Phil Collins's 'In the Air Tonight' - which incorporate scratching, drum kit, harmonica, brass, electric guitars and bass - all produced, naturally, with the human voice. Finish time: approx. 23:30
