For 20 years, qParkett presented unparalleled explorations and discussions of important international contemporary artists by esteemed writers and critics. These investigations continue in issue #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. To celebrate qParkett's 20th Anniversary, this year's three issues (#70, 71, 72) will feature special contributions by both artists and writers on the current state of materiality in contemporary art. Scholarly writers look back to how earlier generations of artists employed materials and how this differs from so many contemporary artists' material engagements today. Collaborating artists of the past two decades contribute anecdotes, drawings, and photographs commemorating their experiences with qParkett. Best of all is the inclusion of an additional fourth collaborating artist who will participate in a discussion about his or her relationship tomateriality and will create a new qParkett edition: with Franz West in issue #70, Pipilotti Rist in issue #71, and Alex Katz in issue #72. For qParkett #71, the featured collaborating artists will be Swiss installation and video artist Olaf Breunning; British conceptualist Keith Tyson; and American painter Richard Phillips.In this, as well as through the use of the radio transmitter, it extends McGaffeya#39;s Intermod series (2001-ongoing), which has ...
