Popol Vuh, founded in 1969 by German keyboardist Florian Fricke, was a pioneering force in electronic and world music. Initially embracing the Moog synthesizer, they transitioned to organic instrumentation, blending ambient, psychedelic, and ethnic sounds. Their collaborations with filmmaker Werner Herzog, notably on "Aguirre, the Wrath of God" (1972) and "Nosferatu the Vampyre" (1979), are acclaimed. Their 1972 album "Hosianna Mantra" is considered a classic, influencing genres like new-age and ambient music.
