I don't know if it's on Spotify, but King Crimson recorded a multi-disc live album ca. 1974 in part at the Palace Theater in Providence. The whole first disc and first two tracks off the second are supposedly from the Providence concert.

Notably, one of their improvised pieces from that night was later edited/mastered for release on their seventh studio album, Red. The track is rather aptly named "Providence".

edit: should probably add that full live album is titled "The Great Deceiver" if you wanted to look it up!
