The artist duo YoHa alias Matsuko Yokokoji and Graham Harwood 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 their long time collaborator, Richard Wright, to produce the installation 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.
