In the Court of the Crimson King was released on the 10th of October, 1969. Upon its release, the album reached No. 5 on the
UK Albums Chart this problem was compensated for by
EQ until 2002. Fripp speculated that the problem was caused by incompetent
mastering engineers or "some tapes were mastered in different countries on machines that were not very well maintained or from copies made in the source country (normally US or UK in the case of rock music) where the second machine was inadequately maintained/monitored. These tapes were then sent out to licensee countries who had no adequate measure of comparison and trusted the source material from the record company office. Tape machines running at different speeds occasionally resulted in albums being a couple of seconds shorter/longer". In 1982,
Mobile Fidelity Sound Lab released a
half speed mastered version of the album on vinyl,
cut by Stan Ricker with the Ortofon Cutting System. In 1989 the album was remastered for its debut on CD by
Robert Fripp and Tony Arnold; this version was part of "The Definitive Edition" series, which consisted of other remastered albums by the band. In 1999, in commemoration of its 30th anniversary, the album was remastered again, this time using 24 bit and
HDCD technology by
Simon Heyworth, Robert Fripp and
David Singleton; this edition was part of the "30th Anniversary Edition" series, which consisted of remastered editions of King Crimson's back-catalogue for their 30th anniversaries. Three years later, in 2002, the original masters were discovered in the
Virgin archives, with splicing tape still present between the various songs, and crossfade between "
I Talk to the Wind" and "
Epitaph" yet to be created. In 2004, a new remaster was done by Simon Heyworth using these first-generation stereo master tapes and it was released the same year with a 12-page booklet. This release was called "Original Master Edition" and used the same HDCD and 24 bit technology as the 1999 remaster. In October 2009, Fripp collaborated with musician and producer
Steven Wilson to remix the original master recordings in a new stereo and
5.1 surround sound mix, released as the album's 40th Anniversary edition. The album was sold as three different packages: a two-CD set with the old and new stereo versions, a CD and DVD set with the new stereo and surround sound mixes, and a six-disc (5 CD/1 DVD) box with all mixes and bonus audio and video tracks. In 2010, the original 1969 stereo mix was remastered and reissued on 200-gram super-heavyweight vinyl. This edition was cut by John Dent at Loud Mastering, it was approved by Robert Fripp and included a download code for a 320 kbit/s transfer of the original 1969 vinyl. In 2019, the album was remixed in 5.1 and stereo by Steven Wilson once again for a 50th anniversary box set of the album. Wilson expressed satisfaction with his 2009 remix, but stated that his 50th anniversary mixes are a significant improvement, being more faithful to the original 1969 mix and benefitting from his 10 years of ensuing experience. The box set includes 3 CDs and a
Blu-ray. The Blu-ray features the all-new 2019 stereo and 5.1 mixes encoded at 24/96 resolution, the 2004 "Original Master Edition" with the 1969 mix (also encoded at 24/96), a complete alternate version of the album comprising 2019 Steven Wilson mixes and 2019 instrumental mixes, while the three CDs in the box set feature the new 2019 stereo mix, an expanded edition of the alternate album in the Blu-ray and the "Original Master Edition" plus additional tracks. == Critical reception ==
