Banksy's work started in the Bristol underground scene, which had collaborations between artists and musicians. According to graphic designer Tristan Manco and the book "Home Sweet Home", Banksy "was born in 1974 and raised in Bristol, England. The son of a photocopier technician, he trained as a butcher but became involved in graffiti during the great Bristol aerosol boom of the late 1980s". His style is similar to Blek le Rat, who began to work with stencils in 1981 in Paris, and to members of the anarcho-punk band Crass, which did a graffiti stencil campaign on the London Underground system in the late 1970s and early 1980s.
