Aguirre soundtrack: only 2 of 9 tracks are actually from the film — the rest are compiled from early-'70s Popol Vuh sessions

Only “Aguirre I” and “Aguirre II” on this album are actually from the film. The remaining tracks were pulled from various Popol Vuh recordings between 1972 and 1974 — it’s more of a curated compilation than a straightforward film soundtrack.
