Some fans of the binge-watching, couch-potato variety know the band BETTY for its catchy theme song for The L Word and its regular appearances on the Showtime series. Highbrow fans might also know of the group’s appointment as Arts Envoys for the U.S. Department of State, and activists are familiar with the extensive work its members have done for the LGBTQ community and for women’s empowerment worldwide. Beyond those accolades, however, BETTY is a fun-loving group of gals that seriously rock. At the Arthur M. Sackler Gallery, get to know them in a completely different way: as part of Darren Waterson’s new installation, “Filthy Lucre.” The band will contribute live music to create a multi-sensory experience. “Filthy Lucre” uses the famed Peacock Room as inspiration, showing it in decay to illuminate the intersection and struggle between art and commerce. BETTY knows this well, having found a balance between its presence in the entertainment industry alongside its members’ work as humanitarians. BETTY performs at 5:30 p.m. at the Arthur M. Sackler Gallery, 1050 Independence Ave. SW. Free. (202) 633-4880. asia.si.edu.
