They're calling it "Dancing for Dara" -- Sat., March 5's all-day art exhibition, video screening and dance party to help out the video artist with local ties.

Greenwald is the partner of Josh MacPhee, who's an original member of Justseeds, a nationally known arts cooperative whose distribution center is located in Pittsburgh.

MacPhee was also guest curator of Paper Politics, last year's fine show of politically engaged poster art at Downtown's Space Gallery. Greenwald herself co-curated of Signs of Change: Social Movement Cutlures 1960s to Now, at CMU's Miller Gallery.

Greenwald was diagnosed with cancer this past summer is undergoing chemotherapy. She lives in Brooklyn, but friends are organizing benefits for her all over the country (with recent events in Baltimore and New York).

The March 5 events in Pittsburgh take place at two venues. From 1-5 p.m., visit Justseeds' place in Lawrenceville (3410 Penn Ave., second floor, enter in rear off Spring Way) for an exhibition of MacPhee's own prints, posters, zines, T-shirts and more, and a Justseeds sale benefiting Greenwald.

Then at 8 p.m., just up the hill, Brillobox (4104 Penn Ave.) hosts a video screening organized by the esteemed Video Data Bank of Chicago. The program of nine video shorts includes work by Pink Bloque, Jem Cohen, Paul Chang, Greenwald herself and others. 

That's followed at Brillobox by a 10 p.m. dance party, with DJs Mary Mack, Square Peg, Drop That and Amor Secreto.

Tickets for the screening, party or both are on a sliding scale of $5-20. Pay $15 or more and they'll throw in a T-shirt.

If you're dancing, bring dollar bills for requests for the DJs.
