Fripp at the time said after the concert had finished that the band had "moved from sound to silence .The gigs in Japan had been called The Completion Tour, they had previously announced on their American tour that they would not be returning.

3 out of the 7 in the current line up are in their 70s and two are in their 60s . No doubt there may be some more music to come perhaps as KC , perhaps as partnerships, but I think its doubtful that the current line up ( which aside from Reiflins illness and death has pretty much been the same for the past 7 years or so ) that has done such an excellent job of representing their back catalogue is going to continue to do that.
