“The first song is 21^st Century Schizoid Man, and it’s such a stellar, freaky track. You don’t really think of it as being made by these incredibly high-minded musicians; you just go, ‘Wow, that’s fucking insane!’

“It’s a whole different matter when you sit down and try to play the stuff, though. You have to be pretty musically accomplished to pull off King Crimson. A lot of head scratching is involved: ‘How are they doing all of these things?’

“The rest of the record has some pretty mellow moments. I don’t know if it ever gets to pure jazz, but there’s elements that are certainly jazz influenced. ‘Prog rock’ as a term wasn’t being used at the time of this record – I don’t think it was – so King Crimson were doing an art rock and psychedelic thing. But they laid the groundwork for a lot of prog with this album.”
