After last year's sell-out shows as a duo with Steve Rutherford, and playing guitar on Sydney Carter's songs and poems with Gordon Funky Socks choir, Mark returns to the Fringe with a show highlighting his songwriting and musical collaborations. There will be songs inspired by science, love, spirituality, loss, the city of Edinburgh and emptiness. Mark's music has been used by the BBC and featured on Celtic Music Radio. He is playing in Scotland's oldest concert hall with a unique oval shape and exquisite acoustics.
