I recommend to check the website of dool.cz crew from Kladno (city near Prague), which counts approximately 12 members and producers of jungle and drum'n'bass style. You can download their promo sets, their own music or glance at some pics from actions. Btw, on May 14th Mystif and Niacin play in ostravian Fabric on FutureBreakz (feat. Larry+, Flu and Elvis).
