This darker, more aggressive sound appealed to many in the dancehall and reggae communities. A shared emphasis on rhythm and bass, and the tempos were well suited to be mixed together. Soon many elements of dancehall reggae were being incorporated into the hardcore sound, and a precursor to what would become known as simply jungle was sometimes dubbed hardcore jungle. The Jamaican sound-system culture began to influence the emerging sound through the use of basslines and remixing techniques derived from dub and reggae music, alongside the fast breakbeats and samples derived from urban musics such as hip hop, funk, jazz, and r&b alongside many production techniques borrowed from early electronic music such as house, and techno.
