In the “Freedom Summer” of 1964, hundreds of young people—including James Chaney, Andrew Goodman, and Michael Schwerner—were drawn to the deep South to take part in the Civil Rights movement. At the same moment, two groups of young men (including guitarist John Fahey and Dick Waterman, the great champion of the Blues) made the same trip in search of Blues legends Skip James and Son House. That these two quests ended in the volatile state of Mississippi, whose governor famously referred to integration as “genocide,” is the starting point for Sam Pollard’s inventive, musically and historically rich film.
