Live In Hyde Park, London is a live album by the band King Crimson, released through the King Crimson Collectors' Club in September 2002. The album documents King Crimson's performance at the Hyde Park Festival of July 5, 1969, held in London, UK. It has been estimated that half a million people attended this outdoor concert, which was headlined by the Rolling Stones. King Crimson were the opening act. Their setlist was cut for the occasion, and the last track was much shorter than usual. Nonetheless, the consensus was that their performance was a success, which significantly increased the band's reputation.
