The Science and Art of Forensic Facial Reconstruction

6 to 7 p.m. National Museum of Health and Medicine, 2500 Linden Lane, Silver Spring. 301-319-3300.


YouTube OnStage

R&B singer John Legend headlines this one-time-only concert, which features popular acts who jumpstarted their careers with viral YouTube videos. The line-up features dubstep violinist and “America’s Got Talent” finalist Lindsey Stirling; Les Twins, the dancing sibling duo from France who’ve appeared with such celebrities as Beyoncé and Missy Eliott; and Scott Bradlee and Postmodern Jukebox, the group famous for its old-timey renditions of modern pop hits, such as their big band swing cover of Beyoncé’s “Drunk in Love.”

7:30 p.m. Kennedy Center, Opera House, 2700 F St. NW. 202-467-4600.


Zombie Book Club

If you don’t feel like the recent popularity of zombies has made them lose their brain-chomping, blood-stained charm, head to the Lamond-Riggs Library to join its newest book club. Dedicated to all things undead, the Zombie Book Club is open to teens and adults. It’s a fun, new spin on the traditional book club in which members are invited to share their favorite books and make zombie-themed crafts, rather than participate in a discussion of an assigned text.

6:30 p.m. Lamond-Riggs Library, 5401 South Dakota Ave. NE. 202-541-6255.


From the Vaults: Jazz Diplomacy

The National Archives screens a series of films about the U.S. government’s use of jazz music during the Cold War. Such artists as Dizzy Gillespie, Duke Ellington, Thelonious Monk, Louis Armstrong and Miles Davis served as "jazz ambassadors," performing in Communist countries and meeting with citizens and heads of state in an effort to improve America’s image abroad. The film screening is a part of the Jazz at the National Archives, a series of panel discussions, screenings, concerts and family activities.

Noon. National Archives, William G. McGowan Theater, 700 Pennsylvania Ave. NW. 202-357-5000.
