Iration Steppas is a UK-based sound system and dub music production collective from Leeds, England. Founded in the early 1990s by Mark Iration, the group took its current form in 1993 when he was joined by partner Dennis Rootical. Their musical style combines traditional Jamaican dub with electronic influences and deep bass frequencies. They are associated with the evolution of the UK dub movement, particularly the "steppers" style.
