Unbegrenzt was recorded by Catherine Christer Hennix (recitation, percussion and electronics) and Hans Isgren (bowed gong) in 1974 and is the Swedish artist's realisation of Karlheinz Stockhausen’s piece of the same name. The Stockhausen original was released by Shandar as part of Aus Den Sieben Tagen (1969), a collection of 15 text pieces written in Paris in May 1968 and which, without notated direction, offered poetic cues aligning with the concept of intuitive music, a form Eurocentric improvisation. Here the realisation expands on Hennix's work with infinitary compositions, a concept central to her work with the ensemble The Deontic Miracle.

It follows Selected Early Keyboard Works and Selections From 100 Models Of Hegikan Roku, as well as a two volume collection of Hennix’s writings titled Poësy Matters and Other Matters.

Unbegrenzt was restored and mastered by Stephan Mathieu. Including an essay by Bill Dietz, Unbegrenzt is released on 28 August by Blank Forms Editions and Empty Editions.
