I’m not a musical ignoramus either — former professional guitar player and arranger, magna cum laude graduate of Berklee College of Music decades ago. I am very open to music of foreign cultures. Developed a love of East Indian music — which has no vertical harmony at all — in high school. I like Japanese koto music, middle eastern music, African drumming and singing. But you couldn’t pay me to sit through a concert of traditional American Indian music.
I wouldn’t want to offer you roast opossum either.
Also consider the music and the message are integral with Native American. They don’t go for flights of abstract instrumental fancy like our Bach or Beethoven, call that a deficiency if you will, but it is a different cultural viewpoint. Let the narrative that goes with the music be translated alongside, and now see if it means something. Even Edward MacDowell was able to get moods out of it.
