“Red” is a great album. Much different than “Court of the Crimson King,” Other than Robert Fripp (the only constant among all the KC albums), it was a completely different album.
The biggest drawback of the albums of that period of King Crimson was John Wetton. Not that great a vocalist, great bass guitar player.
In that regard, Beat is somewhat significant in the King Crimson catalog - it was the first album to use the same lineup as the previous album. And Beat was King Crimson's tenth album!
