1) Copenhagen, Denmark: For years the trio has been busy producing one album after another under the moniker "Future 3". While this project, however, over the years turned more and more into popmusic, Knak (known as well as Opiate and producer of the important tracks on the recent Vespertine), Remmer (aka Dub Tractor) and Skaaning (aka Acustic) realised, besides a big variety of other influences, a common love for Dub and the sonic trademarks of this music: Reverb, Echo & Bass.

2) There is also a band called System in Stockholm, Sweden. It consists of two members called Herr A and Herr B who formed System in the early 90s. They play electronic retro synth pop.

3) MC System, also known as Mark, started his MC career on London's Pirate Radio station Rude FM. He was at one time a part of the Future Thinking crew who throw drum'n'bass parties in the London area. His production style is reminiscent of the old Reinforced Records and Metalheadz sounds.
