Electronic dance music was highly successful throughout the decade in Europe, particularly in Britain, Germany and Italy. Outdoor raves were popular at the start of the decade in the UK, before the government introduced its Criminal Justice and Public Order Act 1994, leading to a higher number of superclubs opening. Among the most successful were Ministry of Sound and Cream. Before the ban, popular genres at these raves included breakbeat hardcore and techno, though in the mid-1990s these genres splintered into separate scenes, such as happy hardcore, jungle and drum and bass, the latter of which received mainstream recognition through artists such as Goldie and Roni Size.
