Does anyone else have this boxset (or the sampler). I just picked this up yesterday, and I must say its excellent. Its amazing that a band that has such ditailed and structured songs can also be great at improves...
I have it and it is incredible, but not for the typical daily Crimson dose. I would only recommend it for hardcore fans.
Your comment about them surprisingly being good at improvisation is a bit strange though... the band is wholly based in the technique and always has been!
