Marillion, a U.K. rock band formed in 1979 in Aylesbury, is credited with establishing the neo-prog subgenre and has influenced acts like Porcupine Tree, Radiohead, the Pineapple Thief, and Gazpacho. Initially known for their flamboyant lead vocalist Fish, they achieved commercial success with albums like Fugazi and Misplaced Childhood before continuing to evolve through various musical styles and lineup changes. After Fish's departure in the late '80s, Marillion remained on the progressive side of rock, exploring genres like post-punk pop, indie, experimental rock, and electronica, culminating in their 2017 release, FEAR.

Throughout their career, Marillion has released a diverse array of albums, blending classic symphonic prog rock with mainstream rock influences. Following Fish's departure, the band continued to experiment and evolve their sound, with successful releases like Afraid of Sunlight and Marbles. Their discography also includes politically motivated works like Sounds That Can't Be Made and the provocatively titled FEAR. Marillion's dedication to their craft and continuous evolution has garnered them a loyal fan base and critical acclaim, showcased through their extensive discography and dynamic live performances.
