In the Wake of Poseidon is the second studio album by English progressive rock group King Crimson, released in May 1970 by Island Records in Europe, Atlantic Records in the United States, Philips Records in Australia, and Vertigo Records in New Zealand. To date the album is their highest-charting in the UK, reaching number 4.
The album was recorded during a period of instability within the band owing to a fluctuating lineup. It follows a very similar musical style and track sequence to their first album, In the Court of the Crimson King. The album was well-received by contemporary critics, who commended the overall execution and production quality as an improvement over that of the band's debut, although later assessments have faulted its heavy reliance on the template established by its predecessor.
Ian McDonald and Michael Giles left the band following their first American tour in 1970. Around the same time Greg Lake was approached by Keith Emerson to join what would become Emerson, Lake & Palmer. With the absence of McDonald, Robert Fripp took on part of the keyboard-playing role in addition to guitar. As Lake's position in the band was unclear, then-unknown Elton John was booked to sing on the recording sessions for In the Wake of Poseidon, but Fripp had second thoughts and cancelled the booking.[1][2] Lake ultimately decided to leave, but agreed to sing on the recordings, negotiating to receive King Crimson's PA equipment as payment. He ended up singing on all but one of the album's vocal tracks. The exception was "Cadence and Cascade", which featured a guest vocal by Fripp's old schoolfriend and teenage bandmate Gordon Haskell. An early mix of the song with Lake singing a guide vocal was later unearthed and featured on the DGM site as a download.[3] Other musicians involved with the album were Michael Giles and his brother Peter Giles on drums and bass respectively, Mel Collins (formerly of the band Circus) on saxophones and flute, and Keith Tippett on piano.
During the recording of the album in early 1970, Fripp, Lake, Tippett and the Giles brothers appeared on Top of the Pops miming "Cat Food". This would be King Crimson's only appearance on the show.[2]
With the album on sale, Fripp and Sinfield remained in the awkward position of having King Crimson material and releases available, but no band to play it. They kept Mel Collins and Gordon Haskell on board, with Haskell also handling bass as well as vocals. Drummer Andy McCulloch, another Dorset musician moving in the West London progressive rock circle, who had previously been a member of Shy Limbs (alongside Greg Lake, who recommended him to Fripp) and Manfred Mann's Earth Band, was also recruited.
The album opens with an a cappella piece called "Peace – A Beginning". An extended version of this piece, "Peace – A Theme", adds a middle eight and is performed on an unaccompanied acoustic guitar. This track appears at the beginning of side two, perhaps conceived as the mid-point of the album, and a third version, "Peace – An End" appears at the conclusion of the album. "Peace – An End" is to some extent a combination of the other two versions, containing both vocals and acoustic guitar as well as the middle eight, but the lyrics are entirely different from those of "Peace – A Beginning".
