"Ung Dansk Kunst's Tapeserie [Young Danish Art's Tape Series] from 1969 is a series of 10 tape works, created by a central group of visual artists of the 1960es' experimental Danish art scene. The tape series is one of the earliest Danish examples of visual artists creating works of art in sound. Sound works that were conceptually, self-consciously and explicitly something other than music. The tapes could be purchased by mail order, and were initially limited to 20-30 copies each.
The 10 works were published all at once and were announced in the leaflet Ta' Information, where five advertisement-like descriptions, designed by the artists themselves, presented five of the works in the series. The work consists of a two-hour recording of Bjorn Norgaard humming. Non stop and with no edits. The recording is rough, it crackles and distorts and bears the marks of being made without consideration for sound quality or microphone technique. It sounds like Norgaard is humming "“ as one does "“ anything that comes to mind. Everything he can think of. Phrases by Vivaldi, Beethoven and bits of Aida and several children's songs pop up in the course of the two hours. 'Indtil doden udfrier mig' can be considered a performance "“ or action, which was Norgaard's preferred term "“ on tape. Not as a documentation, but as a mediated performance which takes place in real time as one listens to the tape. The recording time is reflected in the listening time, the work's time directly mirrors the listener's. 'Indtil doden udfrier mig' utilizes the same strategy as many of the happenings of the time: Simple, more or less unmotivated actions performed consistently and mechanically by the performer, who does not act in a fiction, but performs as themself in the same reality as the observer "“ with the difference that the tape piece transposes the listening experience from the performance in time and place.
