Drum and bass music originated in the UK from breakbeat hardcore, the original rave music of the 1990s. Over the next few years, it began incorporating elements from many genres like dancehall, electro, funk, hip hop, house, jazz, and pop into its heavy, high-energy beats. The scene expanded across the UK in various rave venues, which British ravers enjoyed. Drum and bass is most associated with London and Bristol. Lighter variations with a more "jungle" or "liquid" feel helped expand its audience beyond just hardcore ravers. Some producers then focused on darker, more aggressive sounds, known as darkcore or darkside hardcore, incorporating strange sounds and rearranged funk beats
