The band formed in Germany in 1972. The band members moved to England in 1974 where they merged with Henry Cow, but the merger ended soon afterwards and Slapp Happy split up. Slapp Happy`s sound was characterised by Dagmar Krause`s unique vocal style. From 1982 there have been brief reunions to work on an opera, record a CD and tour Japan.
