For 20 years, Parkett presented unparalleled explorations and discussions of important international contemporary artists by esteemed writers and critics. These investigations continue in issue No. 70, which features collaborations by Swiss-American visual artist and composer Christian Marclay, Polish painter Wilhelm Sasnal and British video artist and photographer Gillian Wearing. Each of these artists has carved out a unique manner of working with the mediums of sculpture, painting and photography, respectively. As well, each artist extends the use of film and video to reflect political, social or popular culture. Authors include Ingrid Schaffner, Philip Sherburne, and Philippe Vergne on Marclay; Meghan Dailey, Gregor Jansen and Adam Szymczyk on Sasnal; and Gordon Burn and Dan Cameron on Gillian Wearing, with a conversation between Cay Sophie Rabinowitz and Wearing. Also in this issue: Greg Hilty on Rebecca Warren, Dominic van den Boogerd on Aernout Mik, Catherine Wood on Mark Leckey, Carolee Thea on Joan Jonas, and an insert by Nic Hess.
