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 Bublé.
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.
