Jungle is a music that developed from hardcore in England in the early 1990's. Early jungle tunes were often based around a sample from The Winston's Amen Brother played at 45 rpm. Jungle later became known as Drum and Bass, and various sub genres emerged/were invented, including Jump Up, Hard Step, Intelligent, Tech Step and Dark Core. Innovaters include Photek, 4-Hero, Ed Rush and Roni Size. Jungle music is not as high profile as it was a few years a go. This is partly due to too much emphasis being placed on "intelligent" drum and bass, which suggested that the rest was "stupid" jungle. In this time Speed Garage has stolen a lot of its following.
