"Parkett" 91 features collaborations with Yto Barrada, Nicole Eisenman, Liu Xiaodong and Monika Sosnowska. In photography and video, Yto Barrada interrogates borders, both geographic and economic. Here her work is discussed by Nuria Enguita Mayo and Urs Stahel, and in a conversation with Eyal Weizman. Nicole Eisenman paints portraits of her community of artists and writers; Jess Arndt and Litia Perta take their turn portraying Eisenman, while Erica Kaufman, Matt Longabucco and Ariana Reines contribute poetic responses. Monika Sosnowska examines the promises and failures of modernist architecture. Here, Francesco Bonami, Brian Dillon and Joanna Mytkowska consider her projects. Liu Xiaodong depicts marginalized groups in a realist style. Hou Hanru and Charles Merewether offer their views on the artist, who also engages in a dialogue with Philip Tinari.
