Question:
King Crimson are an English progressive rock band formed in London in 1968. King Crimson have been influential both on the early 1970s progressive rock movement and numerous contemporary artists. The band has undergone numerous formations throughout its history of which 21 musicians have been members; since October 2017 it has consisted of Robert Fripp, Jakko Jakszyk, Tony Levin, Mel Collins, Pat Mastelotto, Gavin Harrison, Jeremy Stacey and Bill Rieflin. Fripp is the only consistent member of the group and is considered the band's leader and driving force.
After their first US tour, King Crimson was in a state of flux with various line-up changes, thwarted tour plans, and difficulties in finding a satisfactory musical direction. This period has subsequently been referred to as the "interregnum" - a nickname implying that the "King" (King Crimson) was not properly in place during this time. Fripp became the only remaining musician in the band, with Sinfield expanding his creative role to playing synthesizers.  Fripp and Sinfield recorded the second King Crimson album, In the Wake of Poseidon, in 1970 with the Giles brothers hired back as the session rhythm section, and with jazz pianist Keith Tippett and Circus saxophonist Mel Collins as guest musicians. The group considered hiring Elton John to be the singer, but decided against the idea. Lake then agreed to sing on the album in exchange for receiving King Crimson's PA equipment, except on "Cadence and Cascade", which is sung by Fripp's friend Gordon Haskell. Though Tippett was offered band membership, he preferred to remain as a studio collaborator, performing with the band for a single gig. Upon its release in May 1970, In the Wake of Poseidon reached No. 4 in the UK and No. 31 in the US. It received some criticism from those who thought it sounded too similar to their first album. With no musicians to perform material from their new album, Fripp and Sinfield persuaded Haskell to join as singer and bassist and recruited Andy McCulloch as drummer, retaining Collins as saxophonist, flautist and occasional keyboard player.  During the writing sessions for the third album, Lizard, Haskell and McCulloch had no say in the direction of the material, since Fripp and Sinfield wrote the album themselves, bringing in Tippett, Mark Charig on cornet, Nick Evans on trombone, and Robin Miller on oboe and cor anglais as additional musicians. Haskell sang and played bass. Jon Anderson of Yes was also brought in to sing the first part of the album's title track, "Prince Rupert Awakes", which Fripp and Sinfield considered to be outside Haskell's range and style. Lizard featured stronger avant-garde jazz and chamber-classical influences than previous albums, as well as Sinfield's upfront experiments with processing and distorting sound through the EMS VCS 3 synthesiser. It also featured complex lyrics from Sinfield, including a coded song about the break-up of the Beatles, with almost the entire second side taken up by a predominantly instrumental chamber suite describing a medieval battle and its outcome. Released in December 1970, Lizard reached No. 29 in the UK and No. 113 in the US. Described retrospectively as an "acquired taste"., Lizard was certainly not to the taste of the more rhythm-and-blues-oriented Haskell and McCulloch, both of whom found the music difficult to relate to. As a result, Haskell quit the band acrimoniously after refusing to sing live with distortion and electronic effects. McCulloch also departed, leaving Fripp and Sinfield to recruit new members once more.

Question:
Steeleye Span are an English folk rock band formed in 1969. Still active today, along with Fairport Convention, they are amongst the best known acts of the British folk revival, and were among the most commercially successful, thanks to their hit singles "Gaudete" and "All Around My Hat". They had four Top 40 albums and achieved a certified gold record with sales of "All Around My Hat". Throughout their history, Steeleye Span have seen many personnel changes.
Reported difficulties among band members saw a split during the recording of Bedlam Born. Woods reportedly was uncomfortable with the financial arrangements of the band, health problems forced Johnson into retirement, and drummer Dave Mattacks' period as an unofficial member came to an end during this time.  For a while the band consisted of just Peter Knight and Tim Harries, plus various guest musicians, as they fulfilled live commitments. Rick Kemp resumed playing with the band at some of these gigs, with Harries switching to lead guitar. This was an uncertain time for the future of the band, and when Harries announced he was not keen to continue his role, even the willingness of Kemp to return to the line-up full-time was not enough to prevent what was effectively a break-up.  In 2002, Steeleye Span reformed with a "classic" line-up (including Prior), bringing an end to the uncertainty of the previous couple of years. Knight hosted a poll on his website, asking the band's fans which Steeleye songs they would most want to see the band re-record. Armed with the results, Knight persuaded Prior and Genockey to rejoin, coaxed Johnson out of a health-induced retirement, and along with Kemp and Knight, they released Present--The Very Best of Steeleye Span (2002), a 2-disc set of new recordings of the songs.  But Bob Johnson's health prevented him from playing live shortly before the 2002 comeback tour, and he was replaced at the eleventh hour on guitar by Ken Nicol, formerly of the Albion Band. Nicol had been talking with Rick Kemp about forming a band when Kemp invited him to play for the tour, and this was to herald a significant return to form for the band.
