FREESTYLE SKATEBOARDING ART NYC Don’t miss the waning days of this dynamic exhibit co-curated by Rick Krieger and Jim Furlong. “Freestyle Skateboarding Art NYC” gives gallery recognition to a group of contributing artists working in the mediums of paint, sculpture and skateboards decks — to convey the grace and skill of skateboarding in the concrete jungle. The featured artists (all fair game for an informative trip to the gallery, and Google) include David Bowles, Dwayne Caprietta, Cecile Chong, Sarah Coffman, Dedleg, Roberto De Jesus, El Hase, Dylan Goldberger, Claire Gottfried, Christopher Goutos, Gillie Holme, Charles Kopelson, Peter Leitch, Meryl Meisler, Nino B., Danielle Poletto, Robert Poletto, Michel Poulin, JJ Rudisill, Matt Ryan, Wank Longboards and William USA. At Hudson Guild Gallery, Elliot Center (441 W. 26th St., btw. 9th & 10th Aves.). Through Nov. 19. The viewing hours are Tues.-Fri., 10am-7pm and Sat., 1-4pm. For info, visit hudsonguild.org. CHELSEA OPERA: “THE MEDIUM” Chelsea Opera’s season eight opener is a mainstage production of “The Medium” — a dark drama set during a bogus séance. Frightened by a pair of hands around her neck, the titular character dismisses her clients and begins a search for the truth that leads to murder. The composer Virgil Thompson (a former Chelsea Hotel resident) called it the most gripping operatic narrative he has witnessed in many a year, declaring it to be “deeply touching and terrifying.” Thurs.-Sat., Nov. 10, 11, 12 at 7:30pm (also Nov. 12, at 4pm). At St. Peter’s Church in Chelsea (346 W. 20th St., btw. 8th & 9th Aves.). For tickets, call 866-811-4111 or visit chelseaopera.org (in advance, $35 preferred seating, $30 general admission, $20 for seniors and students — all prices higher at the door).
