i ordered this collection after being recommended it while i was dj’ing some american indian music at the bottom of the hill. i’m thankful to whoever it was that told me about it, these records are fantastic, and in their original shrink wrap from 1972. don’t sleep! i have no idea how many sets they have, but even though they’re mono i highly recommend this collection. and only $50 for 23 records! so far the peyote record is my favorite. if you only want to try one at a time, get that one. american indian music is like tribal house music, except without houses.
