The weekend’s best in nightlife, music and art. For even more, check out Nightlife Agenda.

Friday-Sunday: Somewhere between Tilda Swinton sleeping in a glass box at the Museum of Modern Art and local artist Kathryn Cornelius's seven public betrothals and divorces on a single day at the Corcoran, the art world officially succumbed to performance-art fever. The trend is alternately ephemeral, interactive and endurance-testing, but is nearly impossible to define, so it’s best to experience it for yourself this weekend at Supernova, the area's first festival of performance art. The festival includes more than 100 free performances across Rosslyn by artists such as J.J. McCracken, Jeffry Cudlin and Cornelius.

Friday-June 30: Fans of unpredictable theater -- and particularly those with short attention spans -- will love the Source Festival's mix of full-length plays, 10-minute shorts and the program's "Artistic Blind Dates," when artists from different creative disciplines collaborate on unexpected new works. The festival begins Friday at 8 p.m. with "In the Midst," a block of six 10-minute plays.

Saturday-Sunday:  Capital Pride saves the best for last. The 10-day celebration of the city's LGBT community peaks with the annual Capital Pride parade on Saturday. This year's route extends from 22nd and P streets east to 14th and R streets NW, passing through the Dupont Circle and Logan Circle neighborhoods with a phalanx of glittery drag queens, scantily-clad performers and community supporters marching in solidarity from 4:30 to 7:30 p.m. On Sunday, events culminate in the Capital Pride street festival, on Pennsylvania Avenue from noon to 7 p.m. with three stages of music, vendors, two beer gardens and food. Visit for a parade map and the complete list of scheduled performers.

Saturday-Sept. 1:   While Picasso's name is more synonymous with cubism, the French modernist Georges Braque played an equally significant role in the genre's development. The Phillips Collection's new exhibition, "Georges Braque and the Cubist Still Life," places 44 of Braque's still-life paintings from 1928 to 1945 within the historical and political framework of the years leading up to World War II.

Saturday: Asia After Dark, the fun music-meets-food-meets-art garden parties at the Freer and Sackler, return for the season on Saturday with a Korea Soul Train theme. The dress code? Gangnam-chic, naturally.

Saturday: Stick around after Saturday's 4:05 p.m. Nats game to see Blues Traveler kick off the NatsLive summer concert series, which features musicians performing for fans after games (you need a game ticket to see the bands). Future concerts include Thompson Square (July 6) and Gavin DeGraw (Aug. 3).

Saturday-Sunday: Consider a family road trip to Baltimore's National Aquarium for World Oceans Day, a two-day celebration of water (it will also be celebrated at National Aquarium in the District). Games, crafts and other activities both inside and outside of the aquarium introduce visitors to the world under the waves and offer tips on how to protect it.

Saturday: When it comes to introducing Shakespeare's prose to new audiences, trust the Tony Award-nominated Washington playwright Ken Ludwig. Take "Shakespeare in Hollywood," his 2003 play in which Puck and Oberon end up on the Warner Bros. studio lot circa 1934 and Elizabethan fairies are set loose on show business. Ludwig's newest project is "How to Teach Your Children Shakespeare," a book for parents that Ludwig will sign and discuss at noon at the Folger Shakespeare Library.

Sunday: The D.C. Jazz Festival is in full swing. Hear CapitalBop's edgy offerings Sunday at the Fridge, where Gerald Cleaver’s Black Host tops a lineup that kicks off at 8:30 p.m. Check out more of the D.C. Jazz Festival's best shows here.

Sunday: Local "taste of" festivals are ubiquitous this time of year. One of the oldest is the Taste of Wheaton festival, which returns Sunday with fare from the Limerick Pub, Hollywood East Cafe, Moby Dick Sushi, as well as a wine and food tent stocked with Maryland wines (tastes are $1 to $5).

Sunday: Union Market will have a distinctly Mediterranean feel Sunday from noon to 5 p.m. during the Israel @ 65 food, wine and music festival. Listen to performers such as Mosh Ben Ari and the Mama Doni Band, have a drink in the Israeli beer and wine garden, browse crafts, watch cooking demonstrations by local chefs and nosh on shawarma, falafel and Kosher-style and vegetarian food truck fare. While you're there, be sure to look out for the new Suburbia summertime frozen-drink dispensary.

A previous version of this post said Gerald Cleaver's Black Host would perform June 6 at the Fridge. The show is on Sunday.
