Friday // 6 p.m. // Bronx Museum of Art [1040 Grand Concourse, Bronx] // Free

BLOCK PARTY: Hopefully the annual Habana Outpost Block Party this Saturday as they stir up the streets of Ft. Greene. The eco-eatery will take over for twelve hours, delivering "live music, a designers market, kid's entertainment, hot dj's and much more!" Check out all the details here.

Saturday // Noon // Habana Outpost [757 Fulton St, Brooklyn] // Free

THEATER: On Wednesday night, Samuel Beckett’s Endgame opened at BAM in a revival that expertly finesses Beckett’s simultaneous embrace of bitter humor and pitiful horror. The stellar ensemble features John Turturro as Hamm, Max Casella as Clov, and, cowering in Beckett’s iconic nursing home trash cans, Alvin Epstein and the incomparable Elain Stritch. To see it is to inhale all the hilarity and misery of life in a single breath. As Turturro tells The Nation, “the play really deals with that: when everything's taken away, what really do you have? You have another person, maybe, to torture or to love, or to both.” – John Del Signore

Saturday // 2 p.m. & 7:30 p.m. // BAM Harvey Theater [651 Fulton Street] // Ticket prices vary.

DERBY: Spring has sprung and it's time to get your fancy hat on, your mint julep refreshed and lay down a bet on the Kentucky Derby. Do all of this, and more, at Pete's Candy Store this Saturday -- there will be hat contests, door prizes, live music, equestrian pageantry, bluegrass, BBQ and more!

Saturday // 3:30 p.m. // Pete's Candy Store [709 Lorimer St, Williamsburg] // Free

MOVIE: You may have some sense of the vibrant squalor of Rio De Janeiro's sprawling slums from movies like City of God, but now’s your chance to see the drug-infested chaos through the eyes of the unlucky cops assigned to them. In Elite Squad, a collaboration between City of God’s screenwriter and a former military police officer, most of the cops are predictably corrupt, but the movie focuses on a hardcore Green Beret-type police squad caught in the crossfire. It’s a gripping and graphic wide-angle look at the hellish drug war; today’s screening is the last chance to see it as part of the Tribeca Film Festival. [In Portuguese with English subtitles.] – John Del Signore

Sunday // 11 a.m. // AMC Village VII [66 3rd Avenue] // Tickets cost $10

EVENT: PopRally presents a screening of Graffiti Research Lab: The Complete First Season, which will be followed by a panel discussion with GRL (and others) and a reception (party!) on the 6th floor of the MoMA. The film "documents the adventures of an architect and an engineer who quit their day jobs to develop high–tech tools for the art underground. Featuring insightful and humorous commentary by GRL founders James Powderly and Evan Roth, The Complete First Season argues for free speech in public, open source in pop culture, the hacker spirit in graffiti, and not asking permission in general."

Sunday // 8 p.m. // MoMA Titus Theater

Sunday // 9 p.m. // Pacha [618 West 46th St] // $20adv/$30dos
