This tape piece is my response to ``The folk-rnn Session Book Vol. 1 (of 10)''. The title is because I was struck by the sense of unease felt by some musicians when I describe the work of the folk-rnn team and system. The tunes from the folk-rnn collection are all numbered, and I used the house numbers of places in Belfast I’d lived during my life as a starting point to select particular tunes. For example, 55 (Delhi Street); 34 (Malone Avenue). The melodies played here on concertina are composed by the computer, having learned from collections of notated traditional music. The piece played here by computer, is composed by me from recordings of my playing as I learned the computer’s compositions. We each play the other’s work, and the work is made from the process we each went through, of learning the other’s material.
