Returning to the UK, drum and bass (as jungle) has its direct origins in the breakbeat hardcore part of the UK acid house rave scene. Hardcore DJs typically played their records at fast tempos, and breakbeat hardcore emphasised breakbeats over the 4-to-the-floor beat structure common to house music. Breakbeat hardcore records such as The Prodigy's "Experience" (1992) Top Buzz 'Jungle Techno!' (1991), A Guy Called Gerald's 'Anything' (1991), Shut Up and Dance's "£10 to get in" / "£20 to get in" (both 1989), the Ragga Twins' "Spliffhead" (1990) & '18 Inch Speaker' (1991), Rebel MC's 'Wickedest Sound' (1990), 'Coming On Strong' (1990), 'Tribal Bass' (1991) & 'African' (1991) Nightmares on Wax's 'Aftermath' & 'In Two Minds' (1990), Genaside II's "Sirens of Acre Lane" (1990), DJ Dextrous' "Ruffneck Biznizz" (1992), Noise Factory's 'Be Free' (1992), Demon Boyz 'Jungle Dett' (1992) and LTJ Bukem's "Demon's Theme" (1992) are generally credited as being among the first to have a recognizable drum and bass sound.
