Glottal Wolpertinger was initially conceived as a radio installation for documenta 14 with each of the tracks broadcasting individually over the course of ten weeks and culminating in a convergence of all eight tracks at a performance in Athens. The pieces consist of microtonally tuned feedback, multispectral drones which Werner modulated and filtered with a purposeful, and indeed vocalized, emphasis given to the different frequencies and textures used. Sonic elements churn and sprawl across the tracks in constant motion. Their drones, combatting for space, entangle one another and oscillate into overtones that shift, build, and wither with fluid motion that blurs the line between consonance and dissonance.

Glottal Wolpertinger’s incarnation as a recording is no less potent than its preceding forms, but serves as a continuation of the project’s evolution as a distinct listening experience. Werner’s apt title for the project embellishes the ambiguity and cognitive dissonance inherent with the work, as the wolpertinger is a creature of European myth which is said to be the mutated result of different species breeding under special circumstances in the Alps. Glottal intonations are those produced by the guttural and throat region of the body, the center of organic sound.
