Recently I bought a Lacie portable firewire LightScribe CD burner. It means I can burn a CD and inscribe words and pictures onto the body of the CD while on the move. In theory I could be making CDs on the train.

It occurred to me that I'm not far off being able to record a gig on my laptop as I'm playing it and then burn CD copies of the recording afterwards while having a few pints, and selling them on the spot. I could even give dedications to audience members during the gig, so that their CD would be "personalized". Or play a request!

Then I thought maybe you could take a leaf out of the visual artist's book. A painting is expensive because it's a one-off. So you could record your gig, and make one CD then and there – one CD only – and charge £20 for it. Or auction it then and there. Artwork and dedication would be entirely personal and unique. Obviously, you'd need to be a bit of a name, with a fairly loyal following for this to work...
