Artist duo YoHa alias Graham Harwood and Matsuko Yokokoji have lived and worked together since 1994. They co-founded the artists group Mongrel and established the Mediashed, a free-media lab in Southend-on-sea. In 2008 they joined long time collaborator, Richard Wright, to produce Tantalum Memorial, winning the transmediale.09 award. YoHa have created various projects using 'free media', 'eco-media' and 'social telephony'. Their work explores the complex relationships between power, art and media in a globalized world.
