Micheal Giles and Ian Mcdonald left the band to do solo work. The three of them still in the band, Robert Fripp, Peter Sinfield, and Greg Lake, released the single "Catfood/Groon". On the next album, woodwind player Mel Collins, singer Gordon Haskell, and Peter Giles all helped record a few songs with the band. King Crimson released their second album, In the Wake of Poseidon, in 1970. It was not very popular because it sounded too much like the first album.
