In 1967, drummer Michael Giles and his brother, Peter, a bass guitar player, started a band with Robert Fripp. They recorded one album called The Cheerful Insanity of Giles, Giles and Fripp. This album did not do very well, and a lot of critics wrote bad reviews of it. After this, Ian Mcdonald joined playing keyboards, reeds, and woodwind instruments. Ian McDonald's friend, Peter Sinfield, joined to write lyrics, and Greg Lake replaced Peter Giles on bass guitar. Then they bought a mellotron, which helped them sound more like classical music. They changed their name to King Crimson, and did their first show in Hyde Park, London in 1969. Their first CD, In the Court of the Crimson King, was a huge success. Their original style impressed fans and critics.
