The front cover text runs as follows:

'One of the prime functions of AMM is to try and realise the objectivity of music. Basically all music is subjective (personal), but sound is objective (measureable) [sic], and it is only through sound, by listening, that we can arrive at the reality of music. In this way an audience is absolutely vital to an AMM improvisation. We have to constantly test the music and ourselves in the light of the close scrutiny which an audience places the performer. The audience provides the listening capacity into which we place our sounds, and we try to complete and expand this capacity which completes and expands ourselves at the same time. We play for the listeners, and we accept and respond to the influence that they have upon us and the music. Without an audience, no matter how small, this music would not exist; at least not on the same scale and with the same beauty and intensity as it does when brought out by an audience.'
