I went through a FIERCE UK hiphop period, and I still listen to quite a bit of it now.
Hardnoise, Hijack, Son Of Noise, Party A La Mazon, Blade, Mello, London Posse, Demon Boyz (helped invented jungle, apparently with "Junglist" track on the flip of Glimity Glamity), Black Radical Mark II, Unanimous Decision and of course, Manchester's finest: First Offence (worst hiphop group EVER)
