In response to these lighter tracks, some producers started focusing on darker, more aggressive sounds; this style became known as darkside hardcore, or Darkcore. Strange noises and effects, syncopated rhythms made from rearranged funk breaks and loud bass lines defined the genre. Examples of darkcore include Goldie's "Terminator" (1992), Doc Scott's "Here Come The Drumz", and Top Buzz's "Living In Darkness" (1992). These took their cue from the darker sounds of 'Belgian Techno', as found in tracks such as Beltram's "Mentasm" and "Energy Flash" (1991), as well as the dark breaks of 4 Hero's "Mr Kirks Nightmare" (1990) among others. These tracks were not widely called jungle or drum and bass by the mainstream media at their time of creation (although the terms "hardcore jungle" and "jungle techno" were in common use in the rave scene by then, with "drum & bass" appearing here and there on particular mixes of several vinyl releases), but they can nevertheless be found on later jungle and drum and bass compilations. The first major round-up of these tracks which was to use the term 'drum & bass' was probably "The Dark Side - Hardcore Drum & Bass Style": a compilation on React Records, released March 1993, which featured both "Here Comes The Drumz" and "Terminator".
