Madness is a British pop and ska band from Camden Town, London, England that was formed in 1976. As of 2012, the group has continued to perform with their most recognised lineup of seven members, although that has varied slightly over the years. Known for their cheeky humour and musical eclecticism, the band members called a "dysfunctional family", the group was one of most prominent artists in the late-70s 2 Tone ska movement. As their career progressed, Madness moved closer toward conventional pop music and has become one of the most successful British bands of all time.
