As in... a band you like says 'we've written our new record, but we haven't recorded it yet - we need your money to help us do it', or even 'we haven't written our record yet...'.
So they offer a deal where you pay your £10 or whatever and some months later you get a special CD with your own little credit or loads of bonus goodies or some such thing. Basically like these kickstarter thingies that they do now...
1) Have you done this?
2) Would you do this? Why/why not?
3) Is it 'the future'?
DiScuss. (do people still say that?)
