Brazilian Psych Rock

i have been searching for a cd by this fucking band with this song on it for ages. fucking Itunes doesn't have any mp3s i can download. i first heard this song in the end credits of the documentary Manda Bala. This version is a sort of folky traditional arrangement, but the version from the film shreds with some hotshit guitar work. If someone can find me that version from the film they will be my best friend.
