Discipline is the eighth studio album by the band King Crimson, released in 1981. This album was King Crimson's first album following a seven-year hiatus. Only founder Robert Fripp and later addition Bill Bruford remained from previous incarnations. The rest of the band was Adrian Belew (guitar, lead vocals) and Tony Levin (bass guitar, Chapman Stick, backing vocals). The album resulted in a more updated 1980s new wave proto-techno sound mixed with the previous dark and heavy sounds of the 1970s.
