thank you man, I can't think of good key words or phrases when i'm searching. i just type in google "native american chants" "navajo chants"i will try first nation music. what also sucks is that the bandwidth in my area is really messed up due to technical problems with my ISP so I can't really do any quality searches.could find a good amount on youtube by typing in 'first nation music' or something of the like. pow wow is also a good keyword (for chants/drums), OST's are probably a good bet.and....i didn't read the op...not really much i could do to help in that regard.
Ya, another option, if you don't wwant to get involved in illegal sampling-- PM me here (I've been scolded for posting a bot-disguised e-mail address), and I can do a short session for you and send files or a CD. Have the drums, percussion, and Native American flute... Just give me a tempo.
