Earthbound is a live album by the band King Crimson, released in 1972 as a budget record shortly after the line-up that recorded it had broken up. It is notable for containing the band's first official live release of their signature song "21st Century Schizoid Man," and an extended live version of their 1970 non-LP single "Groon." It also contains two improvised tracks with scat vocals from Boz Burrell.
