Marillion are a British rock group. Formed in Aylesbury, Buckinghamshire, England in 1979, their recorded studio output comprises fifteen albums and is generally regarded as comprising two distinct eras, delineated by the departure of original vocalist & frontman Fish in late 1988 after their first four albums, and the subsequent arrival of replacement Steve Hogarth ("h") in early 1989. Marillion has thus far released eleven albums with Hogarth.
