Blues master Taj Mahal recalls that the 1958 single “Rumble”—by Link Wray, who was born to Shawnee parents—actually made him “levitate out of bed about four feet” the first time he heard it. Filmmaker Martin Scorsese marvels (in a good way) at “the aggression” he heard in its thumping power chords. But Wray’s music—along with that by other indigenous artists—never reached the audiences it deserved. This engaging movie, which won a special price for “masterful storytelling” at Sundance, is out to change all that. Using playful recreations and little-known stories, as well as concert footage, audio archives, and interviews with living legends, it reveals the ways some of our most treasured artists found their inspiration in ancient, native melodies, harmonies, and meaning. You’ll never listen to rock and roll the same way again.
