Marillion is a British rock band formed in 1979, famous for its role in the 1980s neo-progressive rock movement. The band's distinct sound is characterized by poetic lyrics, complex song structures, and the emotive vocals of lead singer, Steve Hogarth, who replaced original frontman Fish in 1989. Notable for their 1985 album 'Misplaced Childhood', which included their biggest hit, "Kayleigh", Marillion has made significant contributions to progressive rock. They are also recognized for pioneering the crowdfunding model in music, using the internet to engage directly with their fanbase for funding and distribution.
