"Actions!" at the Kitchen Explores Performance Art If early performance art - Allan Kaprow's protopsychedelic "happenings," the Dadaist provocations of Fluxus, the nightmarish nihilism of the Viennese Actionists - was mostly aesthetic, successors like Ron Athey and Karen Finley took an explicitly political turn. Artists came to scrutinize and protest the very conditions and institutions under which art is produced, and married the aesthetic charge of their performances to forthright political action. This weekend at the Kitchen, "Actions!," a performance piece by Simon Leung, looks back on several occasions when those energies were directed at the Museum of Modern Art. Deliberately blurring the lines dividing stage, seminar room and picket line, the show draws on contributions from the dancer Yvonne Rainer, the artist Filip Noterdaeme and the artist activist group W.A.G.E., among others, in its attempt to rethink the roles of "worker," "artist" and "activist" for current social, political and economic circumstances. Tickets are $10; $8 for students and those over 65. For Friday night's show, tickets bought in person between 4:30 and 8:15 are pay what you wish. After Saturday's show, Tim Griffin of the Kitchen will moderate a discussion featuring Mr. Leung and the art historian Julia Bryan-Wilson. Friday and Saturday nights at 8, 512 West 19th Street, Chelsea; 212-255-5793, thekitchen.org. In the Miser's view, there are food trucks, and then there's the Taco Truck, one of which happens to be a short walk from the Kitchen. It's a perfect spot for a quick, reasonably priced and thoroughly enjoyable bite before the show. Wednesday and Thursday from 11 a.m. to 4 p.m., and Friday through Sunday from 11 a.m. to 7 p.m.; West 15th Street and 10th Avenue, Chelsea; 646-957-7725, thetacotruck.com. With the Mets long out of playoffs contention and the Yankees coming up short of a wild-card spot, baseball fans in New York have had to endure another season without the prospect of a subway series. Music lovers, on the other hand, are covered, thanks to the Orchestra of St. Luke's Chamber Ensemble, whose own "Subway Series" of free concerts this weekend hits Brooklyn and Staten Island (which is included, even though the borough isn't reachable by subway). On Friday night, the group will perform at the Granite Prospect in Brooklyn Bridge Park, against the glittering backdrop of Lower Manhattan. On Saturday afternoon, the ensemble will set up in the lush Tuscan Garden at Snug Harbor Cultural Center on Staten Island. The hourlong set features brass, and works ranging from Elizabethan court music to "West Side Story." Concertgoers can also donate nonperishable food items there for City Harvest. (Friday at 7 p.m. at Pier 1, Old Fulton Street at Furman Street, Brooklyn Bridge Park, Dumbo. Saturday at 2 p.m. at Snug Harbor Cultural Center, 1000 Richmond Terrace, Livingston, Staten Island; 212-594-6100, oslmusic.org.)
