Arijit Singh at EagleBank Arena: In America, Arijit Singh is far from a household name. But in his homeland of India, Singh is renowned as one of the country’s brightest stars. The 29-year-old singer, composer and producer has built a massive cannon of (often romantic and soulful) songs used in various Bollywood films. This weekend, he brings those songs (and maybe a few others) to life for an audience in Fairfax during his American arena tour. 8:30 p.m. $79-$499.

Prince tribute at Dodge City: The night Prince died, DJ Dredd took to the turntables at Dodge City for a cathartic four-hour set of hits, b-sides and rarities that had fans both singing and crying on the packed dance floor. Dredd, the founder of the Prince vs. parties at the Black Cat and 9:30 Club, returns to the U Street bar to mark the first anniversary of Prince's passing. Get there early. 6 to 9 p.m. Free.

National Cannabis Festival at RFK Stadium’s festival grounds: District residents and visitors can congregate in celebration of cannabis culture at this festival, taking place just a few days after 4/20. Attend educational sessions, grab a bite from a food vendor and hear live performances: This year’s lineup includes Talib Kweli, the Pharcyde, Backyard Band and DJ Ayes Cold. Noon to 8 p.m. $35.

Record Store Day at multiple area locations: Some may scoff at this 10-year-old event, which encourages the public to visit local record stores and buy limited-edition vinyl: 12” singles by Prince and Jane’s Addiction, reissues of Thelonious Monk and Notorious B.I.G. albums, a box with every Ramones single from 1976 to 1979. Most releases are rare, so shops won’t get too many copies. If there’s something you’re dying to have, get to a record store before it opens. Reliable retailers in the Washington area include Crooked Beat in Alexandria, which opens at 9 a.m. with free swag bags for the first 75 customers; Ka-Chunk Records in Annapolis, which will have tote bags and swag for “the first 30-50 people in line”; Som Records on 14th Street NW; and Hill & Dale in Georgetown. Opening hours vary. Free.

Sarah Silverman at the Theater at MGM National Harbor: A comedian whose work has largely focused on mining big laughs from topics such as sex and dating, bodily functions and religion, Sarah Silverman has taken a serious and political turn over the past year. A Bernie Sanders supporter who became an outspoken critic of President Trump, Silverman is taking her left-leaning laughs to Hulu this spring for a weekly show called “I Love You, America,” in which she’ll get to know folks who don’t see things quite like she does. On Saturday, she’ll perform stand-up in Washington. 8 p.m. $54.09-$85.

Crawfish Boil at Bayou Bakery: Louisiana-born chef David Guas knows his way around a traditional crawfish boil. His Arlington restaurant pulls out all the stops on Saturday: Admission includes a pound of crawfish with new potatoes and corn on the cob, plus corn bread, coleslaw and mini-muffuletta sandwiches. (Scarf all that down and you can go back for seconds, while supplies last.) Drink specials include $5 pints and $15 pitchers of New Orleans's own Abita beer. 4 to 6 p.m. $35. No advance tickets.

World War I History Tour at Arlington National Cemetery: One hundred years ago, the United States declared war on Germany, a fight that President Woodrow Wilson said would “make the world safe for democracy.” Learn about the causes, impacts and leaders of the war during a free tour of Arlington National Cemetery led by the cemetery's historians. The two-and-a-half-hour tour includes a visit to the World War I exhibit at the Welcome Center and a viewing the changing of the guard at the Tomb of the Unknowns. 11 a.m. to 1:30 p.m. Free, reservations required.

Brandy Clark and Charlie Worsham at the Hamilton: In Nashville, good songwriting requires great storytelling. So when Brandy Clark and Charlie Worsham — two of the finest singer-songwriters working in country music — share a bill at the Hamilton on Sunday night, expect plot twists every bit as juicy as whatever’s airing then on HBO. 7:30 p.m. $20-$49.50.

D.R.A.M. at Lisner Auditorium: Virginia native D.R.A.M. (which stands for Does. Real. Ass. Music.) broke out last year with the piano and flute-laden “Broccoli,” his Billboard-charting collaboration with Lil Yachty. D.R.A.M. followed up that single with his debut album, “Big Baby D.R.A.M.,” which has thus far spun two more singles: “Cute” and “Cash Machine.” Sunday, the rapper headlines a show on the George Washington University campus. 6 p.m. $30.
