The first New York edition of London's FRIEZE Art Fair doesn't open to the public until May 4, but MoMA PS1 (22-25 Jackson Avenue at 46th Avenue, LIC) welcomes them to the city with a big party on Wednesday, May 2, 8 to 11 p.m. Martha Wainwright will perform a full set in the museum's courtyard dome to kick-off the event. She's planning to include a couple of her famous Edith Piaf covers along with her own music, plus some Kraftwerk-inspired tributes. Later that night there's a DJ set by Mark Ronson. Advance tickets for $25 are still available HERE.
