In The Court of The Crimson King

In the Court of the Crimson King is the debut studio album by the British progressive rock group King Crimson. The album reached number five on the British charts, and is certified gold in the United States.

The album is generally viewed as one of the strongest of the progressive rock genre, where King Crimson largely stripped away the blues-based foundations of rock music and mixed together jazz and classical symphonic elements. In his 1997 book Rocking the Classics, critic and musicologist Edward Macan notes that In the Court of the Crimson King "may be the most influential progressive rock album ever released". The Who's Pete Townshend was quoted as calling the album "an uncanny masterpiece". In the Q & Mojo Classic Special Edition Pink Floyd & The Story of Prog Rock, the album came fourth in its list of "40 Cosmic Rock Albums". The album was named as one of Classic Rock magazine's "50 Albums That Built Prog Rock".

The album was remastered and re-released on vinyl and CD several times during the 1980s and 1990s. All of these versions were based on tape copies that were several generations removed from the originals. The original first-generation stereo master tapes were thought to be lost, but were finally located in a storage vault in 2003. This led to a much improved remastered CD version (see below) in time for the album's 40th anniversary.

Once again, in November 2010 the album was re-released both on vinyl and CD with newly cut masters approved by Robert Fripp. Remastering was executed by Steven Wilson of Porcupine Tree.
