This weekend, the venerable New Art Dealers Alliance (NADA)—known for its expertly vetted annual Miami fair—launches a new art extravaganza, this one within day-tripping distance. A two-hour Amtrak ride to Hudson delivers you less than a block away from an 8,000-square-foot nineteenth-century factory, where NADA Hudson will showcase 50 new projects and installations. Expect a Dia–meets–P.S. 1 vibe, as Lower East Side gallery Invisible-Exports makes free photocopies of not-for-sale works by the likes of Genesis Breyer P-Orridge, Cary Leibowitz, and Rebecca Morris, and art-rockers Bunnybrains and Helado Negro perform (Basilica Hudson, 110 S. Front St., Hudson, N.Y.; newartdealers.org, July 30 and 31; 11 a.m.–7 p.m.).
