"It was like the porn of the music industry."

I just finished watching this fascinating BBC documentary tracing the rise and fall of British prog rock, from Procol Harum to Phil Collins-era Genesis, interviewing almost all the major players in the scene. If you're like me and have a soft spot for bands like Yes and King Crimson, this will make your day. Available on YouTube in three half-hour segments (1, 2, 3).
