Confusion is increased by the term jump-up which initially referred to tracks which had a change in style at the drop, encouraging people to dance. Initially these would usually be breakbeat-heavy drops in this new drum and bass style, but producers of around the same time were creating tracks with hip-hop style basslines at the drop. This would become a new subgenre "jump-up", though many of the early jump-up tracks included edited amens at the drop. Influential artists include DJ Zinc, DJ Hype, Dillinja and Aphrodite amongst many others. The Dream Team would also produce jump-up tracks, usually under the name Dynamic Duo on Joker Records, in a style with similarities and differences to their Suburban Base releases. Notice also the early use of the term "jump up jungle" rather than "jump up drum and bass". The pigeon-holes for genres changed so quickly that jump-up was quickly also called drum and bass even as a subgenre.
