The hour of the monkey — Popol Vuh at the dawn of electronic music. Affenstunde, meaning Hour of the Monkey, is the debut of Popol Vuh and one of the founding documents of electronic and ambient music. Released in 1970, it was among the very first albums to use the Moog synthesizer not as a novelty but as a serious compositional tool.

The short version

The debut album by Popol Vuh, recorded in Munich and released in 1970 on Liberty; two long, dreamlike compositions, around forty minutes. It was the work of Florian Fricke, one of the very first musicians to treat the Moog synthesizer as a serious instrument, and it stands as a landmark in the history of electronic and ambient music. Meditative, mystical and minimal, its synthesizer tones are softened by tribal percussion into a spacious, otherworldly sound. Named after the sacred Mayan book, it helped light the way for Tangerine Dream, Klaus Schulze and the whole kosmische movement.

At the dawn of electronic music

Popol Vuh were the creation of Florian Fricke, a classically trained pianist and sometime film critic, and a friend of the director Werner Herzog, whose films the band would later score. Introduced to the Moog synthesizer by a fellow musician, Fricke became only the second person in the world to own one of the huge modular machines, at a time when synthesizers were a rare and expensive curiosity. He named his new project after the Popol Vuh, the sacred book of the Maya, reflecting a lifelong fascination with spiritualism, philosophy and world cultures. Where earlier Moog records had aimed at accessible novelty, and where later German bands would chase cosmic chaos, Fricke set out to make something meditative and mystical. Affenstunde, recorded with percussionist Holger Trülzsch and sound artist Frank Fiedler, was the visionary result.

The sound

Meditative, minimal, otherworldly electronic music, poised between the ancient and the futuristic. Rather than the bright, tuneful synthesizer sound of its day, Affenstunde offers abstract, spacious soundpainting, with Florian Fricke’s Moog conjuring slow, mysterious electronic landscapes that drift and pulse rather than resolve into melody. Crucially, the synthesizer is tempered by Holger Trülzsch’s tribal, hand-played percussion and by natural, elemental sounds, giving the music an earthy, ritual quality quite unlike the cooler electronics that would follow. The mood is contemplative and mystical, unhurried and immersive, closer to a trance or a ceremony than to a rock album. Tentative in places next to the grand Berlin School records to come, it nonetheless has a unique, spaced-out atmosphere, and a spiritual depth that few electronic records have matched.

The songs

The album consists of two long, side-filling pieces. The first, Ich mache einen Spiegel (I Make a Mirror), is a three-part suite that unfolds slowly through mysterious electronic landscapes and passages of natural sound, its sections drifting between stillness and percussive awakening, inspired by ancient texts. The second is the title track, Affenstunde itself, which builds from tribal percussion and electronic effects into a swelling, improvised synthesis of rhythm and Moog, its theme the evolutionary leap suggested by its name, the hour in which the ape becomes human. Both are best heard whole, as immersive, meditative journeys rather than conventional songs, and together they form a single, transformative experience.

Reception and legacy

Affenstunde was warmly received on release and is now regarded as a landmark in the history of electronic and ambient music, one of the first albums to use the Moog as a genuine compositional tool and a cornerstone of the German kosmische movement. Its influence runs deep: it helped open the way for Tangerine Dream, Klaus Schulze and the Berlin School, and its meditative, spiritual approach anticipated much of ambient music to come. Some listeners find it abstract or elusive, and its Moog textures can sound tentative beside later, grander electronic works, but its otherworldly atmosphere remains singular. As the starting point of Popol Vuh’s remarkable journey, and a visionary early step for electronic music itself, it holds a special place in the story of Krautrock.

The verdict

A visionary, landmark debut, and essential listening for anyone drawn to early electronic and ambient music — meditative, mystical Moog soundscapes softened by tribal percussion into something timeless. Come to it for its otherworldly atmosphere and its place at the very dawn of the genre, rather than for melody or hooks. Play it whole, quietly, and let it carry you. From here, In den Gärten Pharaos for more of Popol Vuh’s early Moog music, their Werner Herzog soundtracks for their later fame, and Tangerine Dream and Klaus Schulze for the kosmische scene it helped inspire. A quiet cornerstone of electronic music.
