This collection of 37 songs (mostly from out-of-print recordings) remains emotionally intense yet politically articulate. Live and studio performances include duets with Mercedes Sosa, rousing songs with Pete Seeger, Arlo Guthrie and Ronnie Gilbert, passionate vocal collaborations with Rhiannon and Brian Green, a tender lullaby with Inti Illimani, and anthems like Singing For Our Lives and The Great Peace March.
