The thousands of files are at 128kbps (though Cliff has been saving the source WAV files to DVD) and the ID3 metadata tags are just begging to be reworked so that artist and title display properly in iTunes, etc. – but what a heroic and selfless act. The man deserves a medal.
Listening to the music itself is like a window into a time not so far gone in history, but it’s largely been buried because it’s simply not economically viable to release this stuff in large quantities on CD. This is, I’d argue, what the internet is best at – and why we need to change copyright.
