The weekend’s best in nightlife, music and art:

Friday:  You may not know his name, but you've seen his work: Boris Chaliapin is the illustrator responsible for more than 400 Time magazine covers from 1942 to 1970. The National Gallery's "Mr. Time: Portraits by Boris Chaliapin"  exhibition, which opens Friday and runs through Jan. 5,  includes 26 iconic examples of the artist's work, featuring the likenesses of Marilyn Monroe, Harry Truman, Muhammad Ali and others. Each is done in Chaliapin's signature style, which combined a sketch artist's speed (the illustrator often produced a finished product in 12 hours) with a painter's technique.

Adam Mansbach, the author of the tongue-in-cheek, not-safe-for-children children's book "Go the F--- to Sleep," returns to the District on Friday with selections from his latest novel, "Rage is Back," about a graffiti artist who plots revenge against a police-officer-turned-mayoral-candidate who shot one of his fellow taggers. Poets Joseph Ross and Clint Smith join Mansbach for "Spray Paint," an evening of graffiti-centric prose at 6 p.m. at the Folger Shakespeare Library.

Saturday: The Preakness Stakes, the second leg of horse racing's Triple Crown, is one of Maryland's proudest sporting days, when the eyes of the viewing public turn to Pimlico in Baltimore. As for your own eyes: Will you actually see a single horse on Saturday? Depends on whether you're partaking of the InfieldFest (featuring all-you-can-drink beer and performances by Pitbull and the duo of Macklemore and Ryan Lewis) or not. Not in the mood to head to Baltimore? Catch a D.C. viewing party at the Brixton.

Quick: How many Maryland breweries can you name? More than two dozen brewers and brewpubs from across the Free State are bringing at least 125 beers to Frederick for the Maryland Craft Beer Festival. The strength here is depth: For every familiar Flying Dog or Brewer's Art, there's a chance to sample Solomons Island's the Ruddy Duck or Monocacy Brewing, an offshoot of Frederick's Brewer's Alley. Bluegrass bands perform while you sip, and food will be available. Tickets -- $20 in advance -- are going quickly.

The Washington National Opera is preparing for its fifth Opera in the Outfield, a free simulcast of an opera performance for fans stretched out under the stars at Nationals Park. This time, the audience will see the vintage "Show Boat," about a crew of show-business hands aboard the Cotton Blossom. Performed by the WNO, the production will feature a cast of 100 singers, dancers and actors. Gates open at 5 p.m. for the 7 p.m. performance.

Art Museum Day, a national initiative to spotlight art museums, will have some area museums that usually charge admission waiving their fees Saturday — a kind gesture to get you in the door. In Washington, three museums are participating: the National Museum of Women in the Arts, the Corcoran and the Phillips Collection. The Baltimore Museum of Art will also go free.

Dog owners: Dress up your pup and head to Bethesda for a little doggie socializing at Strut Your Mutt, the annual fundraiser hosted by the Bethesda Chevy Chase Rotary Club. The event features a pup parade, costume contest and more.

Saturday-Sunday: The 12th annual D.C. Dragon Boat Festival returns to the Potomac River at Thompson's Boat Center beginning Saturday at 9 a.m. Teams from across the country compete in 250 meter races throughout the day, with the winners advancing to Sunday's races. While the racers are in the water, expect live music and dance performances on the shore.

Sunday: Sure, some of us are wondering if pickled ramps killed rock-and-roll, but if the 9:30 Club's Sound Bites fundraiser with D.C. Central Kitchen promises local meat and couture cocktails while pummeling you with rock, well, at least it's for a good cause. Musical headliners include Lee Fields & the Expressions, Deathfix and DJ Will Eastman. Among the food and drink headliners: Rappahannock River Oysters, Red Apron Butcher, Taco Bamba, Shake Shack and more than 15 others, plus a mixology competition featuring cocktail makers from the Gibson, Bar Pilar, Black Jack and Birch & Barley. (Weekend's Fritz Hahn is one of the competition's judges.)
