Artists discuss the role that Native Americans have played in the development of American popular music.
Very well done documentary. Deeper than expected.
Undoubtedly there are those who already knew/know all this but I'll call it revisionist history because it certainly revised my history of American music.
I only knew of Jim Pepper ('Witchitai-to') and Jesse Ed Davis (with Taj Mahal) before watching this. I knew of Buffy Sainte-Marie but I always felt badly because I couldn't stand her vibrato.
If you have near-musicology level interest in the history of blues, jazz and rock, served with another healthy dose of delightful American cultural history, here you go.
