"Drumfunk, sometimes referred to as "edits" or "choppage", is a subgenre of drum & bass . The term came into widespread use ca. 2000, when drumfunk itself began to expand. The hallmarks of drumfunk records are complex breakbeats, which sound as though they are being played live on a drumkit, but are usually composed of samples which have been processed and rearranged electronically. The first drumfunk track is arguably 'Witchcraft' by Krust and Roni Size which dates back to 1994.
