Claus Poulsen was in the audience and shared these observations with the readers of ET at the time. “Robert didn't even look once at the audience during the concert. But I'm sure we meant something to him. Anyway, it seemed he enjoyed himself, smiling and watching Belew closely - a lot of communication between them in the front line. Same thing in the back line. Several among the audience were truly shocked at hearing Trey's bass sound and fast lines on the Warr. Pat was seriously trying to smash those goddam plastic pads (it seemed) -powerfull. He's a very expressive player and you can watch his face how he's doing. Sometimes troubled during a tricky passage. Then he's angrily attacking the drum kit like a whirlwind. Then smiling sweetly during the highlights. Interesting orchestral / industrial stuff. More, please!”
Pat and Trey’s Heaven And Earth forms the bulk of Improv 1 containing some fine soloing from both Belew and Fripp. As Claus might say - more please!
