Irresistible aural ecstasy from international a cappella stars the Magnets, who will rock the spectacular McEwan Hall with their glorious vocal harmonies and jaw-dropping beatboxing for one week only this August. Celebrating a decade of Fringe highs, the top selling music act at the 2013 Festival return with a feel-good show that will put a grin on your face and a six-part harmony in your heart. Highlights include a mash-up of Pharrell Williams' hit Happy with Chaplin's classic Smile, and another show-stopping mega-medley. A sonic phenomenon you have to hear and see to believe **** (Guardian).
