King Crimson. This 1970 concert, recorded by the BBC has as close to the original lineup as possible.

I've often wondered what would have happened, had King Crimson never existed in the first place. So many bands from 1969 on owe so much to the pioneering work of Robert Fripp and company. I'm sure someone would have come along, and maybe the direction would have been totally different. Or maybe it would have stayed frozen in time.

No. The nice part about music is that it constantly changes - it never quite stays the same. That's what's great about it.

And that's what was so great about King Crimson - they were constantly evolving.
