Alex 'Stormy' Mundy has blown the cobwebs off King Crimson's first session at Air Studios in January 1974. The Crims had gathered there to begin work on Starless And Bible Black. These previously unreleased 10 minutes of outtakes find Bruford, Wetton, and Fripp busy trying to nail The Great Deceiver. There's a short extract of the session up on YouTube. . .
Or you can download the whole thing track. . .
