I still have somewhere a LP record published in the mid 80s by the band "Kissing the pink" in which one track contains a program for the BBC microcomputer. IIRC, the track once recorded on tape and run would produce video effects to be played along with the album songs. Never had the chance to try it however, as I had a C64 and the BBC micro over here was less than unobtanium. Those (actually a few years before) were the years of new wave music, and many small bands were experimenting with microcomputers before MIDI made things much easier. I still recall a friend of a friend of a friend interfacing 8 different electric shavers to the C64 user port then composing tunes for them. It was hilarious enough to be picked up and transmitted live on a local FM radio station. Good ol' days...
