it was recorded on 6 may 1972 at the congregation hall of st. maria unter dem kreuz. despite the title, it is not a live album in any conventional sense, but instead is a transcription of a cassette tape recording of a rehearsal session. in the liner notes, klaus dinger described the recording as a "non-public test/self-audition with eberhard kranemann for a series of 6/7 concerts later in '72". the sound quality of the tape and the resulting cd is generally regarded as poor, with clearly audible tape hiss and distortion.
