It’s a bucket list kind of week here in LA. By the end of the month, you could say you’ve watched a play in a cave (the final showing of the aptly titled CAVE at Griffith Park) and challenged an indie-rock icon to a dance-off (Arcade Fire’s been doing this at some of their shows). As always, check Groupon for even more great things to do in Los Angeles. Renegade Craft Fair Downtown | Saturday, July 26–Sunday, July 27, 11 a.m.–6 p.m. The international celebration of handmade arts and crafts is swinging through Grand Park, inviting locals to check out hundreds of DIY vendors. In addition to shopping for prints, clothing, stationery, and countless other goods, you can also hit up the food-truck lot and listen to tunes spun by KXLU DJs. (200 N. Grand Ave.; free) Cowabunga! 30 Years of Teenage Mutant Ninja Turtles Silver Lake | Through July 27 With three decades under their ninja belts as sewer-dwelling crime fighters, the Heroes in a Half Shell are now officially a common interest of parent and child. In celebration of the live-action movie coming out next month, the iam8bit gallery has curated a family-friendly exhibit of TMNT-themed art from artists around the world. (2147 W. Sunset Blvd.; free) CAVE Griffith Park | Friday, August 1, 7 p.m. For this site-specific play, you won’t just be expected to turn off your cell—you’ll also be expected to hike. Audiences meet a half-hour before curtain time, then trek up to Bronson Caves to watch the story of a false prophet who has sequestered his family in fear of an upcoming apocalypse. (Bronson Caves; $20 suggested donation; buy tickets here) Arcade Fire Inglewood | Friday, August 1–Saturday, August 2, 7 p.m. The world’s biggest indie band is out to make their first arena tour feel as intimate as possible, greeting fans in lobbies and grooving beside them during dance-offs. Previous shows have included a “Motownphilly” cover and a surprise appearance from Echo and the Bunnymen frontman Ian McCulloch, so who knows that they’ll have up their mirrorball-ed sleeves for the LA crowds. (The Forum, 3900 W. Manchester Blvd., Inglewood; $40–$90; buy tickets here) Eighth Annual Outstanding Art of Television Costume Design Exhibit Downtown | Through September 20 Great costumes make great television more transformative—who hasn’t imagined themselves in Cersei Lannister’s gorgeous gowns or Walter White’s slimming coveralls? Get up close to small-screen style at this exhidbit curated from past conteners for costume-design Emmys, including the sparkly numbers worn in one of last year’s winners, HBO’s Liberace biopic Behind the Candelabra.
