this is amazing. youtube now has an yma sumac documentary up for viewing. i've only watched a bit of it so far but what i've seen is excellent. if something like this was out on dvd i'd buy it. you can view it on the youtube site or you can see it over at pcl linkdump where i learned about it. also on youtube is this short running a comparison(or something) to yma, celine dion and mariah carey. i haven't watched it yet. but it could me amusing or horrifying.
