from liner notes:
The recordings were made on cassette by placing two microphones somewhere between the drumkit and the single amplifier used for guitar, bass and keyboards. They were made in the most convenient way possible, basically for our own interest.

Although we rarely manage to repeat anything exactly, some of the structures arrived at through improvisation are sometimes repeated for the tape recorder, or occaisionally subjected to various interpretations, either for use in live performance or simply to see what happens.
