Nyehaus—art collector and philanthropist Tim Nye's intimate three-floor gallery in Gramercy Park—is actually a converted apartment in the National Arts Club. Showing an eclectic mix of important contemporary artists, the space launched with a Martin Kippenberger exhibition in March 2005 and has since installed large-scale experimental music videos by Tony Oursler and a group of minimalist works by the likes of James Turrell and Robert Irwin. (Each exhibition is accompanied by a handsomely designed publication that qualifies as an objet d'art.) Perhaps because of its location outside of Chelsea, Nyehaus has been able to forge noncompetitive, collaborative relationships with both artists and foundations, allowing it to present historically significant work in nontraditional ways. Yet it's the dizzying modernism of Nyehaus' space (especially in relation to the antiquated, mazelike corridors of the National Arts Club) that can prove the most eye-opening art experience of all.
