The environmental and counterculture movements of the 60s have been inextricably linked since day one. The hippies decried war on materialism while promoting love, kindness and care for the planet. And one of through-lines of this movement was music. This week on Sea Change Radio, we take some time to remember the life of the Grateful Dead’s Bob Weir, who recently died at the age of 78. For many of us, across several generations, the Grateful Dead has been more than a band – it’s a movement that’s all about expanding your community and your mind. We dig into the archives to hear from Weir’s longtime bandmate, Bill Kreutzmann, and listen to excerpts of two interviews we did with Bobby’s late songwriting partner, John Perry Barlow.
