"Hidden Gems" from Smithsonian Folkways features somewhat obscure recordings by well-known musicians and public figures. They often deviate from what listeners have come to expect from these individuals, adding new layers of complexity to their personas and bodies of work. Highlights include Leonard Cohen reading from his book of poetry, Allen Ginsberg singing songs on a harmonium, and country singer Marty Stuart as a flatpick guitar sideman in Red Allen's bluegrass band.
