Chelsea gallerist Sean Kelly has added a whopping six artists over the past 18 months, including big names like Kehinde Wiley, Alec Soth and Terence Koh. To show his burgeoning roster, he’s moving in the fall to a two-story, 22,000-square-foot gallery at 36th Street and 10th Avenue, the current home of nonprofit Exit Art, which is closing after 30 years. It’s three times larger than Mr. Kelly's current space. “The minute we saw it we knew it was the right one,” Mr. Kelly told The Observer. He’d been looking for a year.

“The numbers speak for themselves,” he added. “It’s an enormous amount of exponential growth in terms of opportunities for artists, more space for us, and for accommodating additional staff.”

New York-based architect Toshiko Mori, who has designed Issey Mikaye stores, exhibitions at numerous museums (including the Museum of Modern Art and the Cooper-Hewitt) and the master plan for New York University, is handling the project.

Though it’s a bit north of the main Chelsea grid, the space will be close to the next stretch of the High Line and the Hudson Yards development. And its sheer size puts Mr. Kelly in league with the world’s most powerful dealers, like Gagosian, whose 24th Street location measures 25,000 square feet.

And Mr. Kelly is not stopping here. “We’re refining and extending the program,” he said.

TUESDAY, MARCH 20

Opening: Dustin Yellin at Half Gallery
The weather's warming up so why not brave Half Gallery this Tuesday for an the opening of a new show by Dustin Yellin? Even if you have to wait on the street, which is likely, the weather's fine and you can casually chat with famous people. --Dan Duray
Half Gallery, 208 Forsyth Street, New York, 6–8 p.m.

Opening: Emergency Index at The Kitchen
The Chelsea performance space launches a new annual book series called Emergency Index, which documents performances in the words of their creators.

Miller
The Kitchen, 512 West 19th Street, New York, 7 p.m.

WEDNESDAY, MARCH 21

Opening: Virginia Overton at the Kitchen
Ms. Overton has the rare ability to build grand objects, tinged with a bit of drama, out of quotidian materials. Some examples: three long sheets of plywood propped carefully between columns to form a triangle, an orange ladder wedged between two walls (in SculptureCenter's basement in 2009) and an old Chevy pickup truck sitting in a gallery. She'll have a show at Mitchell-Innes & Nash later this year. Join the fan club now. —Andrew Russeth

THURSDAY, MARCH 22

Opening: "New Traditionalists" at Martos Gallery
This group show unites pieces by three emerging painters—Justin Adian, Jess Fuller and Leif Ritchey—with the evergreen work of veteran B. Wurtz. Ms. Fuller and Mr. Richey make inventive, messy abstractions that sometimes involve fusing or tearing apart fabric, while Mr. Adian wraps bulging slices of foam with canvas and sprays them to a sheen, to make what could be pillows for a pleasure-seeking alien race. Mr. Wurtz uses objects like plastic bags, cans and the like to create what critic Bruce Hainley has termed "winsome and utterly particular things." —A.R.
Martos Gallery, 540 West 29th Street, New York, 6–8 p.m.

Opening: Vibha Galhotra, "Utopia of Difference" at Jack Shainman Gallery
For this solo exhibition, Vibha Galhotra's New York debut, the artist presents sewn metal ghungroos (the bells used to make musical anklets tied to the feet of classical Indian dancers) as well as new sculptures through which Ms. Galhotra continues to explore gender and the environment in contemporary society by using domestic, industrial and natural materials. —R.J.
Jack Shainman Gallery, 513 West 20th Street, New York, 6-8 p.m.

Artist Talk: Georgia Sagri, Whitney Biennial Artist Talk at Columbia University
Georgia Sagri’s piece for the press preview for the Whitney Biennial included her recording and looping this statement: “I’m not doing a performance for the press.” Ms. Sagri uses projections, spotlights, cameras and sound equipment to construct an atmosphere of loops, beats and visuals to explore the way technology informs the way we interact. She returns to her alma mater (’06) to speak about her work. —R.J.
Prentis Hall, Columbia University, 632 West 125th Street, New York, 7:30 p.m.

FRIDAY, MARCH 23

Opening: Grimes at AVA
Claire Boucher, a.k.a. Grimes, is a 23-year old synth pop singer who your little sister probably likes. Stop by Audio Visual Arts this Friday to check out her visual art! "Mob scene" doesn't begin to describe what this will be. --D.D.
Audio Visual Arts, 34 East 1st Street, New York, 6–9 p.m.

Opening: Every Exit is an Entrance: 30 Years of Exit Art
The final exhibition at Exit Art, which was opened in 1982 by Jeanette Ingberman and Papo Colo, culls the alternative space's archives and will include work by a long list of artists. The show is up until May 19, the last day that the space is open to the public before closing permanently. --M.H.M.

One final gala. (Exit Art)

Big changes on the New York alternative-space scene: Exit Art has announced via e-mail that it will close in 2012. Its co-founder, Jeanette Ingberman, died earlier this year, at the age of 59, of cancer.

Over its three-decade existence, the space became known for supporting emerging artists, particularly female and minority artists who were often overlooked by the mainstream art world, and for politically engaged group shows.

In the announcement, Exit Art, which started in SoHo and is now based in Hell's Kitchen, says that it is planning one final gala for March 6, 2012, to fund a variety of retrospective projects, including an exhibition and book, and "asking its longtime supporters for help in sending us out with a bang." The details in the e-mail, linked to by Artnet, are as follows:

"This Gala and Auction is being held to raise funds for Exit Art's "Legacy Project": a 30-year retrospective exhibition, the publication of a major book on the history of Exit Art, and a properly-funded transfer of the organization's complete archives to NYU Fales Library Downtown Collection. At Fales, scholars will be able to study Exit Art, its groundbreaking programs, and the thousands of artists who have shown here since 1982."

More information on the history of Exit Art is available in Ms. Ingberman's obituary.
