Popol Vuh - Hosianna Mantra (1973)

Florian Fricke pioneered the use of synthesizers in German rock, but by the time of Hosianna Mantra he had abandoned them (eventually selling his famous Moog to Klaus Schulze). While In den Gärten Pharaos had blended synths with piano and African and Turkish percussion, Hosianna Mantra focuses on organic instrumentation. Conny Veit contributes electric guitar, but other than that, Fricke pulls the plug and builds the album around violin, tamboura, piano, oboe, cembalo, and Veit's 12-string, often with Korean soprano Djong Yun's haunting voice hovering above the arrangements.
