Friday update: Jazz in the Garden has been canceled due to rain.

Jazz in the Garden at National Gallery of Art’s Sculpture Garden: There are few D.C. summertime staples as enduring as Jazz in the Garden. Every Friday from mid-May to late August, office drones, interns and tourists alike gather at the National Gallery of Art’s Sculpture Garden to sip sangria and listen to live jazz. Sometimes, the music plays second fiddle to the scenery and the hum of conversation. But at this year’s opening show, you should pay special attention to the band, the JoGo Project. Led by former Chuck Brown Band saxophonist Elijah Jamal Balbed, the group fuses go-go and jazz (and a little funk and hip-hop) into something you’d find only in the District. 5 to 8:30 p.m. Through Aug. 24. Free.

'Leonard Bernstein's America' at the Library of Congress: The Library of Congress’s biggest contribution to the Bernstein centennial can be found online: In April, the library posted 3,700 items from his archive online, including manuscripts, scrapbooks and recordings. Its Bernstein centennial concert also seeks to shed light on the less-known, bringing in strong vocalists, including the soprano Julia Bullock, to perform excerpts of three stage works: the operas “Trouble in Tahiti” and “A Quiet Place” and the White House musical “1600 Pennsylvania Avenue,” the composer’s attempt at a definitive American statement. (It flopped on Broadway in 1976.) 8 p.m. Free.

[Leonard Bernstein shaped American music. Here’s how to celebrate him around D.C.]

Greek Festival at St. Sophia's Cathedral: The annual three-day celebration of Greece is best known for its food, including gyros made with lamb cooked on spits, and booths preparing spanakopita, vegetarian casseroles and loukoumades (cinnamon doughnuts drizzled with honey). But the festival at St. Sophia's, located near Washington National Cathedral, also includes live music and dancing, vendors selling jewelry and religious icons, family activities and tours of the cathedral. Noon to 10 p.m. Friday and Saturday, noon to 7 p.m. Sunday. Free.

ChiKo After Dark with Himitsu's Kevin Tien and Carlie Steiner: The latest in ChiKo's guest chef series finds Kevin Tien and Carlie Steiner, of Petworth's acclaimed Japanese restaurant Himitsu, joining Danny Lee and Scott Drewno in the cramped kitchen on Capitol Hill. Tien and Steiner create special dishes and drinks just for the evening — all $8 each — and no reservations are necessary. All you have to do is show up. 9:30 p.m. to midnight. Dishes $8 each.

Iceage at Union Stage: On its first two albums, Danish band Iceage held the punk flame in its hands, harnessing its fire and fury. But on the quartet’s 2014 album, “Plowing Into the Field of Love,” that flame burned down preconceptions of what punk can be as Iceage tossed elements of blues, folk and country into its cauldron. And on the new “Beyondless,” Iceage has gone for baroque, adding horns and strings to caustic epics powered by the haunting growl and literary poetry of frontman Elias Bender Ronnenfelt. “I’m here to supply a demand, like roaring free jazz fireworks,” he sings, and the band delivers on his incendiary promise. 8 p.m. $15-$25.

Saturday, May 19

Royal Wedding viewing parties: Victories in the Revolutionary War and the War of 1812 did nothing to damp Americans’ ardor for the British royal family. Why else would people wake up at an ungodly hour on a Saturday morning to put on fascinators and head out to watch an American actress marry the man who’s sixth in line to the throne? Restaurants, bars and hotels are throwing open their doors before 7 a.m. on May 19 for Meghan and Harry’s wedding. The St. Regis Hotel ($55, 6:30 a.m.) offers prosecco paired with scones, tartines, tea and wedding cake, and the Ritz-Carlton (6 a.m., $75) offers a “decadent breakfast,” themed cocktails and prizes for the best fascinators and ascots. You'll find a more laid-back (but no less passionate) crowd at the Queen Vic pub (6:30 a.m., free) where the special menu includes full English breakfasts and deviled Scotch eggs. (The viewing party at the Royal Wedding Pop-Up Bar is sold out.)

[This British pub has become D.C.’s go-to spot for watching Brexit and the royal wedding]

D.C. Bike Ride: Did you know you burn the same number of calories biking around D.C. streets even when you’re not being honked at by drivers? See for yourself at the annual D.C. Bike Ride, a day when a 20-mile route around the city is shut down to vehicle traffic for an all-ages ride at whatever pace you like. Keep an eye out for musicians providing entertainment along the route, including the Swagg Tyme drum line, percussionist Damien Walker and funk act the Experience Band. Afterward, riders and spectators celebrate at the free Finish Festival right by the finish line on Third Street SW between the Capitol Building and the Mall, complete with live music, food trucks, kids’ activities and a yoga session. Ride begins at 8 a.m. at West Potomac Park. $65-$175 adults, $32.50-$39.50 kids 8-17; free for children younger than 7. Finish Festival runs 9:30 a.m.-12:30 p.m.

Malcolm X Day: The annual Malcolm X Day celebrations in Anacostia Park were major events in the 1980s and early ’90s, with appearances by Public Enemy, Chuck Brown, Spike Lee and Jesse Jackson. After an absence of more than two decades, which organizers attribute to rising costs, Malcolm X Day returns, though it is now expanding to a full week of events. The centerpiece is an afternoon-long gathering in Anacostia featuring go-go legends E.U. and the Melvin Deal African Heritage Drummers and Dancers — both veterans of the ’80s gatherings — plus the Union Temple Men’s Choir, drummers and dancers from Malcolm X Park, and guest speakers. Noon to 6 p.m. Free.

Hawai’i Festival: He Lani Ko Luna at the National Museum of the American Indian: Science and the stars are the focus of this year’s Hawaiian cultural festival at the National Museum of the American Indian. (The name “He Lani Ko Luna” translates to “A Sky Above.”) Learn how Hawaiian mariners have navigated the Pacific Ocean for centuries using the Hawaiian Star Compass, and see a planetarium presentation with astronomers from the ‘Imiloa Astronomy Center of Hawai’i. Also on the agenda: storytelling, food demonstrations and hands-on activities, including knot-tying and lei-making. Saturday and Sunday from 10 a.m. to 5:30 p.m. Free.

Preakness Viewing at Hill Prince: This bar on H Street NE is named after the winner of the 1950 Preakness, so it's appropriate that the bar goes bigger for that race than it does for the Kentucky Derby. The “Maryland AF Party” includes all-day DJs and drink specials, food prepared by Sally's Middle Name and “Old Bay everything.” While the main event has a 6:20 p.m. post time, Hill Prince will broadcast races throughout the day. 3 p.m. to 3 a.m. Free.

SOB x RBE at U Street Music Hall: The West Coast rap renaissance has been an endless parade of new artists ready to “serenade the streets of L.A., from Oakland to Sac-town, the Bay Area and back down,” as 2Pac rapped on “California Love.” The newest of the new is SOB x RBE, a Vallejo foursome with the Voltron-like strength of a basketball team or a boy band, all ready to trade verses full of brash trash talk at the drop of a beat. At its best, SOB x RBE makes breathless, hookless relay races over sped-up samples of ’80s dance tracks, proving that California still knows how to party. 7 p.m. $15.

Sunday, May 20

'Late Night With Leonard Bernstein' at the Phillips Collection: Jamie Bernstein narrates this multimedia program exploring her father’s life and works through his music, photographs and compositions by others with special significance to Bernstein, who was an insomniac (hence the title). Performing are soprano Amy Burton and the pianists Michael Boriskin and John Musto — who is himself a gifted American composer. 4 p.m. $20-$40.

Jazz at Lincoln Center Orchestra: 'A Tribute to Leonard Bernstein' at the Kennedy Center: Bernstein borrowed from many American musical idioms, and they’re happy to borrow right back. Wynton Marsalis and the Jazz at Lincoln Center Orchestra perform a range of arrangements of Bernstein’s greatest hits, presented by Washington Performing Arts. 7 p.m. $45-$105.
