I wrote this in 1990, and recorded it several times, each time bewildered that I couldn’t make a four-track tape recorder sound like a 24-track studio. I realise the Beatles did remarkable things with a four-track, but equally I realise that I’m not George Martin.

I’m not sure which version this is: not the first version, I think, although I remember that as being quite good (though beset with hiss, on account of my forgetting to turn on the noise reduction, although that might have been a different song), probably the second, so 1991 or 1992.

This is a song about n-dimensional geometry, believe it or not. Or at least that’s what I thought at the time. I suppose I liked to comfort myself with the thought that it might be about something.

As I said, it was recorded on a four-track in about 1992, so there is a certain limitation to the audio quality.
