Wow. It's validating to read Thomas Dolby's Blog (TED's musical director) where he's remixed Radiohead's "Nude". Radiohead is going a step further than anyone by offering "Stems" to the song on iTunes, and setting up a remix contest.
Why validating? This isn't just a remix where you mash-up two songs - this is the artist offering-up original unmixed tracks... It's exactly the open-sourcing of music I predicted on my March 4 blog.
Boy, would I love to see other artists begin to do this -- It could be just what the recording industry needs to spice-up the market. Turn fans into an extension of the artists themselves!
