The protest song “We Shall Overcome” became an anthem of the Civil Rights movement, and in light of the Obama inauguration has taken on a different feel. (Heather Carawan’s documentary The Telling Takes Me Home does a wonderful job in presenting the song’s evolution through the century.) In this Pandora performance featuring Marcus Shelby on bass, Matt Clark on electric piano and Jeff Marrs on drums, “We Shall Overcome” becomes like a delicate, eloquent tribute.
