I have lots of records, and lots of favourite records. My favourite FAVOURITE record is 'I Feel Love' by Donna Summer. I could listen to it forever. It's my 'crossing the event horizon and passing beyond relativity into the shapeless, formless, timeless infinite unknown' record.
I've chosen this 'live' appearance because it's astonishing to consider that real people are playing this music, with human hands and minds. A work of evolutionary importance.
