The complete audio history of one of the most important debut albums of all time is presented across 26 discs in this boxed set. Featuring a new Dolby Atmos mix by Steven Wilson, 6 CDs’ worth of session material on CD & Blu-Ray for the  rst time (fully mixed by David Singleton), a further disc of newly compiled studio material, the box also includes the original studio album, every alternate take known to exist, every mix known to exist, all live recordings known to exist & a selection of pre/Crimson 1968 recordings. The set - as with the previous boxed seven sets in the series - is housed in a vinyl sized box complete with a booklet featuring an introduction by Robert Fripp, notes about the source tapes from David Singleton, sleeve-notes by King Crimson biographer Sid Smith, previously unseen photos from the recordings sessions, additional memorabilia & a protective outer sleeve.

The group's definitive album, and one of the most daring debut albums ever recorded by anybody. At the time, it blew all of the progressive/psychedelic competition (the Moody Blues, the Nice, etc.) out of the running, although it was almost too good for the band's own good -- it took King Crimson nearly four years to come up with a record as strong or concise. Ian McDonald's Mellotron is the dominant instrument, along with his saxes and Robert Fripp's guitar, making this a somewhat different-sounding record from everything else they ever did. And even though that Mellotron sound is muted and toned down compared to their concert work of the era (e.g., Epitaph), it is still fierce and overpowering, on an album highlighted by strong songwriting (most of it filled with dark and doom-laden visions), the strongest singing of Greg Lake's entire career, and Fripp's guitar playing that strangely mixed elegant classical, Hendrix-like rock explosions, and jazz noodling. Lineup changes commenced immediately upon the album's release, and Fripp would ultimately be the only survivor on later King Crimson records.
