Can the history of jazz singers, from the 1920s to present, really be presented in one not-so-big room with photos, videos, handwritten letters, and artwork? The Library of Congress answers yes, with an exhibit that draws from its own impressive collection, plus that of curator Larry Appelbaum, a library employee who also DJs at WPFW and writes for JazzTimes. While emphasizing the impact of 20th century greats like Ella Fitzgerald and Billie Holiday, the presentation also honors contemporary acts like Cecile McLorin Salvant and Esperanza Spalding. Highlights include masterfully composed William P. Gottlieb photos from the 1940s, and excerpts from a Louis Armstrong children’s book that explains the art of scatting.

Free. (202) 707-5000. loc.gov.  (Steve Kiviat)
