Sound-art and transmission-art from London sound art collective Gwaith Sŵn. This month they explore the theme of Rhythm. In response to an open call for new work there are pieces from a host of international artists including Sebastien Sequoiah-Grayson, David Nadeau, Varun Krishnan, Kazuya Ishigami, Olaf Baars and Muesli Boys. A big thanks to all who got involved and sent in material. [Repeated Friday 5am.]
