German/English avant-pop group, formed in Germany in 1972. Their lineup consisted of Anthony Moore, Peter Blegvad and Dagmar Krause. 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 create an opera called Camera, record the album Ça Va in 1998, and perform shows around the world.
