In 1975 Popol Vuh released an album entitled "Aguirre". Although ostensibly a soundtrack album to Herzog's film, the six-track LP included only two songs ("Aguirre I (L'Acrime Di Rei)" and "Aguirre II") taken from "Aguirre, the Wrath of God". The four remaining tracks were derived from various recordings made by the group between about 1972 and 1974. At the time of "Aguirre" the band members were Fricke (piano, Mellotron), Fichelscher (electric guitar, acoustic guitar, drums), Djong Yun (vocals), and Robert Eliscu (oboe, pan pipe).
