There is something hearty and comforting about the lo-fi, sharing spirit of this show from geophysicist and musician Steve Garrett. It is, at the end of the day, really no more than a slide show about his experiences working in Antarctica, accompanied by a lecture that is par history, part memoir, and some of his beautiful, gentle guitar compositions. Whether you feel drawn in by the simplicity of one person narrating ideas and experiences to a room, or frustrated by the lack of slickness and stagecraft probably depends on your mood and expectations. 

Garrett is a genial, warm host and has led an interesting life. His research took place at a time when the Antarctic region was barely accessible (now they have around 100,000 tourists a year, he tells us). He took to painting watercolours while there, which he shares alongside his compositions; both are delicate and soporific to meditate on. He has also used some interesting techniques in his musical composition, plotting ice-based carbon dioxide levels into a line graph, which he later transposed into a musical score. This is a show for inquisitive minds and gentle souls, with an uplifting message of hope at the end. 

The Song Of The Ice, Space St Marks, until 28 August, 8.30pm.
