Jungle is the name given to a style of electronic music that incorporates influences from genres including
breakbeat hardcore,
techno,
rare groove and
reggae/
dub/
dancehall. There is significant debate as to whether Jungle is a separate genre from
drum and bass as some use the terms interchangeably. Jungle and Drum and bass started to separate musically in the late 1990s. There is a fuzzy period there where it is harder to distinguish the difference between the two. There is much politics attached to labeling different tracks as a specific genre. Presented here is a choice selection of Ragga/Raggacore & standard Jungle/d&b... a great introduction to anyone interested.

Probably the best Ragga & or Jungle compilation i've heard, with tracks from Archangel, Zebo, KGB Kid & RCola... this is well worth buying, if you cant be bothered to buy it, there are torrents out there, but you gotta find em' yourself.
