Only seats, round theatre setting, with great acoustics and no PA elements visible.
Nice!
And not a single lightshow element used, just a stable soft light on the stage all the time.
Only during the last song the podium got slowly put in diep red light, as a simple sign.
Three drummers in front, the band behind on a higher stage.
No speech or presentation, no show, nothing, during 1 1/2 hour.
Some communication got done with pre-recorded funny meant statements and thoughts about the disturbing use of cameras, phones etc., one by one by all members of the band.
Didn't see any flashes, so that worked

I'm not the guy to please with rock concerts, even not for free, but this was a nice and justified exception.
Nice to see and hear the polyrhitmic (drum) elements devided over three drummers on three exactly the same drumsets -except the specific additions each drummer had.
I wasn't a real fan of King Crimson, although it was a natural part of my musical luggage at the time.
But 'listening back in time' during the concert, the influence of the band on a broad range of rock music is clear.
There just was one song, a bit funky, which made me think of Talking Heads' album Bush, but who was first?
