A review of King Crimson live. In 2015! It makes me pleased that one of the greatest bands of the 20th century is still producing great performances. http://thequietus.com/articles/17026-king-crimson-live-at-the-orpheum-review

And then this in the comments:- For my own part, I think the really interesting part of this equation is the fact that there's clearly a compelling demand from music fans of all stripes for nostalgia as mainstream entertainment. Why do we seem to have developed a morbid inability to just let go of the past? It's like we're participating in the collective recital of a Really Important Dream, lest its details slip away...

"The collective recital of an important dream, lest its details slip away" This. I've recently been listening to FourTet/Floating points 6hr set and then dipping into Caribou's 1000 track playlist. And in both I was struck by their reverence for the late 60s and early 70s mainly in the form of barely remembered soul and funk. Do we have to keep deliberately remembering this to avoid forgetting it? Or is this turning into some tribal memory kept alive by the elders repeating it to each new generation.

btw. Go and listen to "Starless" and "One more red nightmare" again off King Crimson's album Red. And turn it all the way up to 11. Fair makes the hair stand up on the back of the neck. But this is the one that gets me every time. The Letters from the album Islands.
