In the latest episode of “Under the Cover,” contributor Jan Tumlir interviews the multidisciplinary artist Paul Pfeiffer on the occasion of his first US retrospective, “Prologue to the Story of the Birth of Freedom,” at the Geffen Contemporary at MoCA in Los Angeles. Tumlir, who considers Pfeiffer’s artistic output in the pages of the March issue, asks the artist about video looping and repetition, religion, and the artwork Vitruvian Figure, 2008, featured on this month’s cover.
