Also listen to Thrak it has been remastered on CD and 200 gram vinyl. Excellent album with the triple double lineup. There are some great songs on it.
King Crimson
The only knowledge I had of King Crimson was my first LP bought self titled Bad Company, and reading the bass player Boz came from Crimson. Fast forwarded 50 years and I am now hearing for the first time "in the court of the Crimson King". I know I wouldn't have liked what I love today, when I was 13. Amazing players and composers! Court is not dismissed, please remain seated.
