A selection of American folk music that preceded green pop

It’s good to witness the current flourishing of what we might call Green Pop – though others may prefer Eco-Pop, Eco-Rock, etc... - challenging the current state of our environment - PopMatters writes proudly about the new wave of music dealing with climate change, and nature protection. PM presents American folk musicians that preceded them - Woody Guthrie, Neil Young, Chris Webby, Joan Baez, Phil Ochs, Malvina Reynolds, Tom Paxton, Pete Seeger, and Don Maclean.
