The Going Out Guide recommends free things to do for every day of the week:
Kicking off the Crystal City “Crystal Screen” summer film series, Steven Spielberg’s 1982 classic, “E.T.,” recounts a boy’s life-changing encounter with an alien. Featuring a young Drew Barrymore, a glowing finger and those iconic flying bicycles, the film still holds up as a dramatic sci-fi crowd-pleaser.
After sunset, Crystal Screen, 1851 S. Bell St., Arlington. 703-412-9430. www.crystalcity.org/artful/screen.
Since 1988, D.C. band Oasis Island Sounds has been performing the Caribbean-inspired music that founder and bandleader Peter Humphrey played while growing up there. Catch the group’s blend of calypso, reggae and African dance music, complete with steel drums, on the visitors center lawn at Brookside Gardens. Just remember to bring lawn chairs or blankets.
6:30 p.m., Brookside Gardens, 1800 Glenallen Ave., Wheaton. 301-962-1400. www.brooksidegardens.org.
Sometimes, even the best of intentions worsen already difficult situations. Christopher J. Coyne, an economics professor at George Mason University, tackles this issue in his book “Doing Bad by Doing Good: Why Humanitarian Action Fails.” At the Cato Institute, he’ll be joined by a panel of policy experts to discuss the downsides of international outreach.
Noon, the Cato Institute, 1000 Massachusetts Ave. NW. 202-789-5229. www.cato.org.
With ethnic backgrounds spanning multiple continents — the band includes members born in France, Niger and the United States — Sahel is understandably labeled “world music.” At this outdoor concert in Bethesda, the group will showcase its blend of such international styles as zouk, mbalax, samba, reggae and salsa.
6 p.m., Veterans Park, Woodmont and Norfolk avenues, Bethesda. 301-215-6660. www.bethesda.org/bethesda/summer-concert-series.
In this Hispanic-focused event, such Spanish-speaking poets as Marianela Medrano, Astrid Lander and Emilio Mozo will read from their works and discuss the state of Hispano-American verse.
1:30 to 3:30 p.m. Library of Congress, James Madison Building, Mary Pickford Theater, Independence Avenue and First Street SE. 202-882-6227. www.teatrodelaluna.org.
D.C.’s longstanding Capital Pride Parade is a sight to behold. The 1.5-mile journey features all sorts of floats, walkers and entertainment. Alongside drag queens and scantily clad dancers, there’ll be politicians and community members celebrating this year’s “superhero” theme. Expect plenty of spandex.
4:30 p.m., Dupont Circle at Connecticut Avenue NW. www.capitalpride.org.
Spanning three days and multiple venues, the Supernova Performance Art Festival is an ambitious attempt to harness and exploit some of D.C.’s rawest creative energy. Sunday features challenging, unconventional works by such artists as Stephanie Barber and Bonnie Jones from Baltimore and a “grandma parade” at 3 p.m.
Friday from 3 to 5 p.m., Saturday from 7 a.m. to 9 p.m. and Sunday from noon to 5 p.m., Freedom Park, 1100 Wilson Blvd., Arlington. 703-522-6628. www.rosslynartsproject.com/supernova.
