discovery HD people music

[Throttleton]

what is the piece of music used in the discovery HD "people" advert thingy :)?
its a load of clips of various tribal/ native folk from all across the globe doing their own thing. The the word "people" appears on the screen etc. all the way through is this very cool piece of instrumental music that builds up nicely with the add.
that's all the info I can give, but. . . . . . . .
" I gots t know"

thanks all:)
