Following their five-star, fan-favourite run at the Fringe last year, OOTB are back again for their 20th year with tighter harmonies, crazier choreography and enough high notes to reach the stratosphere! Out of the Blue is an internationally acclaimed a cappella group from the University of Oxford and, after jet-setting across the world earlier this year, the group is excited to return to their home turf to showcase new talent and new songs. Don't miss your chance to see these singers in action for an hour of incredible music with something for everyone!
