It’s been nearly three years since we announced our “pay what you think it’s worth” scheme for the launch of our last record In Rainbows. I remember the excitement of it all, not least because the release date was my wife’s birthday, 10 October. The idea came from a friend of our manager, who proposed an “honesty box”, placing the onus on people to ask themselves how much they valued our music. Last summer, as we finished some more recordings, we started to think and talk about how to release them. So it seemed a good moment to take stock of the technological and cultural changes that have happened in the meantime.
