Well, I seem to be the drum and bass guru around here so i will help you out.
Moving from trance to drum and bass i would suggest looking for Logistics, Nu:tone, Commix, High Contrast, and Cyantific. Anything remotely close to Pendulum would be Dara, Dj Fresh, TeeBee, and check out SKC along with Chris.Su
edit: To find mixe's by these artists go to
www.dogsonacid.com and just search, something will pop up, I promise.
