FRIDAY:

>> Tired of putting those great costume ideas on the back burner till October? Dying for a chance to wear a costume without wearing a jacket over top? Three Stars vets New Rock Church of Fire feel the same way. Tonight, join NRCOF, D.C.'s The Gaskets and Richmond's The Invisibles at the Rock & Roll Hotel for July-O-Ween. Incognito fun, rip roaring rock from all three bands, DJ sets, drink specials, a costume contest and more await you. $8, 9 p.m.

>> It's the last weekend of the Capital Fringe Festival, so browse through DCist's coverage of just a few of this year's offerings, or check out The Washington City Paper's extensive Fringe and Purge blog for more, and give one of the hundreds of shows still left to be performed a shot.

SATURDAY:

>> Chicago-based, semi-metal rockers Pelican will perform at the Black Cat with Earth, and Priestbird (formerly Tarantual A.D.). 9p.m., $12.

>> One of Charlie Chaplin's later films, A King in New York, satirizes McCarthyism and America's obsession with fame, and is playing for free at the National Gallery of Art at 4 p.m.

SUNDAY:

>> Classical musicians from D.C.'s professional ensembles will unite under the name Sonus Cura ("caring sounds" in Latin) to present a program that includes choral and orchestral works by Bach (Dona nobis), Copland (Quiet City), Shostakovich (Chamber Symphony OP. 110a), Stravinsky (Octet for Winds), and Martin (Mass for Double Choir), with the proceeds going directly to the Save Darfur Coalition. Suggested donation is $20, performance is at 3 p.m. at National Presbyterian Church, 4101 Nebraska Ave. NW, 20016.

>> TheGoodmanLeague street basketball series hosts the Wizards' own Agent Zero, Gilbert Arenas versus area native Kevin Durant, arguably the best college player last year from last year and the number two draft pick, in a Primetime Sunday game at the Barry Farms Recreation Center basketball courts in Southeast. The game starts at 7 p.m., but this promises to be a zoo, and the web site smartly advises that you "get there early."

>> Don't forget to stop by the Warehouse to pay your respects to Molly Ruppert and her son Paul, as they shutter their cafe and music venue after so many years of providing an amazing arts space for our city. Buy a beer starting around 7 p.m. and chat with them about their future plans, which we hope are big, exciting, and forthcoming.
