Fifty years ago, Johnny Cash performed at Folsom State Prison in Folsom, Calif. The January 1968 concert and live album it produced, At Folsom Prison, helped revitalize Cash's career, inspiring him to testify for prison reform and cementing his reputation as a voice for the downtrodden.

Jorge Drexler is a poet with a gift for song. The Uruguayan singer-songwriter, like the iconic Latin American lyricists of the past (Mercedes Sosa, Victor Jara and Silvio Rodriguez, to name just a few), has that rare ability to surround multi-layered prose with music that lends an even deeper resonance to the words.

Lara Bello occupies the space between genres where magic happens. Born in Spain, she was raised with not only Spanish traditions like flamenco and canto but also pop music and jazz. The instrumentation she assembled for her Tiny Desk reflects that elastic approach to genre: acoustic classical guitar, clarinet, violin and a percussionist who didn't keep time so much as color the proceedings.
