The author notes Fripp disbanding King Crimson in 1974, but doesn't mention the 80s reformation at all (with Discipline, Beat and Three of a Perfect Pair). Or the 90s ("double trio") reformation, or the 00s ("double duo") reformation, or the 10s ("seven-headed beast") reformation.

Though Tony Levin hints that it's over now in <https://tonylevin.com/road-diaries/king-crimson-2021-tour-pa...>.
