Branden W. Joseph is Frank Gallipoli Professor of Modern and Contemporary Art at Columbia University, where he specializes in practices that cross medium and disciplinary boundaries between the visual arts, film, and music. He is the author of Beyond the Dream Syndicate: Tony Conrad and the Arts after Cage (Zone Books, 2008); Anthony McCall: The Solid Light Films and Related Works (ed. Christopher Eamon; Steidl, 2005); Random Order: Robert Rauschenberg and the Neo-Avant-Garde (MIT Press 2003); and The Roh and the Cooked: Tony Conrad and Beverly Grant in Europe (August Verlag, 2011). Additional writings—which include numerous essays on Andy Warhol and John Cage, as well as writings on contemporary artists such as John Miller, Angela Bulloch, Lee Lozano, and Josiah McElheny—have appeared in a wide range of scholarly journals and museum catalogues and been translated into eight languages. Joseph is also a founding editor of Grey Room (MIT Press), a journal of architecture, art, media, and politics, which published the special issue “New German Media Theory” in 2007. Grey Room has featured Joseph’s interviews with political theorists Chantal Mouffe and Paulo Virno and his conversation with Suzanne Cusick, about music’s use in psychological torture.
