We assembled this track to demonstrate the kinds of colorations typical of professional microphones. We had wanted to get as much correspondence as possible between the microphones featured on this track and those used to capture the music tracks. Unfortunately, Gordon had mislaid the Sony C37 mikes used for his music recordings when he moved to Colorado; the Calrec Soundfield mic was not available to us when this track was laid down; and copyright problems meant that two music tracks that were made with microphones featured in this track did not make their way on to the CD.
