Andante (a musical term meaning ‘at walking pace’) follows the cellist Ruth Boden as she climbs 10,000 feet to a peak in Oregon’s Wallowa Mountains for a deeply personal, yet breathtakingly public solo performance. With her prized cello strapped to her back, Boden reflects on how she wants to do something with music that transcends the commonplace, and on the particular joy of playing from Bach’s cello suite at ‘the top of the world’.
