Whether embracing your inner child at an ice-cream festival, reliving your high-school years at a screening of Dazed and Confused, or commemorating the 50th anniversary of the Civil Rights movement, this week’s events give you a chance to revisit the past. As always, check Groupon for even more great things to do in Los Angeles. Street Food Cinema Exposition Park | Saturday, August 2, 5:30 p.m. If seeing Richard Linklater’s much-lauded new film Boyhood has you jonesing for some of his cult classics, this outdoor screening of Dazed and Confused should do the trick. Come early for food-truck fare and indie-rock tunes from local band Speardane, before settling in for the 8 p.m. screening. (700 Exposition Park Dr.; $6–$17; children 5 and younger are free; buy tickets here) People Get Ready: A Soundtrack of the Civil Rights Movement Downtown | Saturday, August 2, 8 p.m. Commemorating the 50th anniversary of the Civil Rights movement, this concert features modern soul and world-music singers performing freedom songs by Billie Holiday, Nina Simone, Bob Dylan, Stevie Wonder, and other legends. The lineup includes French favorites Les Nubians, as well as Sam Cooke’s granddaughters, who’ll likely be covering their grandad’s classics. (350 S. Grand Ave.; free) Once Hollywood | Through August 10 This Oscar-, Grammy-, and Tony-winning story may have moved from Off-Broadway’s modest theaters to the Pantages’ grand stage, but it still centers on the original songs Glen Hansard and Markéta Irglová wrote for the film. If you get there early enough, you can even grab a drink from the onstage bar before the show begins. (6233 Hollywood Blvd.; $32.25–$140.70; buy tickets here) Ice Cream Festival Downtown | Through August 24 At Rosa Mexicano, chefs are throwing a month-long Ice Cream Festival, during which they’re making scoops inspired by their savory, south of the border foods. Flavors include avocado, cinnamon-chili-spiced chocolate, and sweet-corn-and-caramel. If you’re worried how these concoctions might taste, don’t be—Martha Stewart once said the restaurant serves “the best guacamole in the world.” (800 W. Olympic Blvd.; free) Jack & the Giant Sawtelle | Through August 24 In this reimagining of the classic fairy tale, kids in the audience decide the characters' fates by helping them make decisions along the way. The Little Theater's intimate, 49-seat setup eases the interactive process, but come early for a good seat as the venue is first come, first serve.
