The Beatroots, The Ultrasounds

A double dose of acappella! First up: Oxford's only postgraduate acappella group, The Beatroots. They're finalists in this year's Voice Festival UK community competition and won Best Arrangement at last year's festival. Be prepared to enjoy a mixture of pop, rock and jazz delivered through their own imaginative and tongue-in-cheek arrangements.

Meanwhile, The Ultrasounds are Oxford's premier all-male, all-medic acappella group. Their repertoire spans the choicest morsels of popular music from the '60s to the present day. The Ultrasounds provide your recommended daily allowance of musical flair - just what the doctor ordered!
