UB40 are a dub / reggae pop music band formed in 1978 in Birmingham, England.
The band is one of the world's most culturally diverse dub reggae bands with musicians of English, Scottish, Irish, Yemeni and Jamaican parentage. The band is named from the paper form issued by the UK at the time of the band's formation for claiming unemployment benefits (UB40 = Unemployment Benefits, Form 40).
UB40 were influenced by the many Blues Parties they attended as teenagers in the multiracial Balsall Heath area of Birmingham, their love of ska and reggae inspired such original tracks as "King", "Madam Medusa", "Food for thought", "Signing Off" and "One in Ten".
Their early music style was unique, with a heavy influence of analogue synthesizers, psychedelic rock guitar, saxophone and dub producer techniques which were later perfected by the late Pablo Falconer.
Ali and Robin Campbell have a musical heritage, being sons of Ian Campbell, a folk musician.
