Collector and art writer- turned-gallerist Adam Lindemann opened his Madison Avenue Venus Over Manhattan space Thursday to show off “Gang Bust” — an exhibition of paintings by William N. Copley (a k a CPLY) alongside provocative new riffs on the works as curated by artist Bjarne Melgaard. At a Monkey Bar reception, Sid Bass (who hasn’t made many public appearances since his split with society doyenne Mercedes Bass) chatted in a booth with Parker Posey. Guests included gallerists Paul Kasmin and Gavin Brown, Proenza Schouler’s Jack McCollough and Lazaro Hernandez, W editor Stefano Tonchi, Cynthia Rowley and Bill Powers, and Copley’s son William B. Copley.
