I've been searching for this ever since I subscribed to Spotty in 2015, and now finally!!! Thank you Peter G!!! (I assume). Now if we could get King Crimson, esp. Discipline! Be sure to vote for the Wish Box idea.
It is up to King Crimson alone whether their material should be available. Robert Fripp so far has decided he does not want his material to be on Spotify, but the appearance of live albums may hopefully be a sign of different times.
