The artist collective MTAA (M.River & T.Whid Art Associates) produces conceptual and net art works, ranging from interactive online performances to software and sculpture. Primarily working in new media, M.River and T.Whid—pseudonyms for Mike Sarff and Tim Whidden—bring internet culture and the economics of art under the lens. One of their best-known works, 1 Year Performance (aka samHsiehUpdate) (2004), updates the artist Tehching (Sam) Hsieh’s first performance, The Cage Piece (1978–79), in which Hsieh lived in a cage in his Manhattan loft for a year. MTAA reconfigures the piece so that the two artists appear in separate cell-like spaces that can be viewed online over the space of a year via what look like webcams. The videos of M.River and T.Whid are in fact looped recordings that demonstrate the ability for new media to alter the perception of time.
