Drunkfunk is a subgenre of Drum and Bass which has many origins from all corners of the Drum and Bass spectrum. Drumfunk takes influences from Rave, Jungle and early Drum and Bass to give a very distinct sound. It has been around in one form or another since synthesizers were able to chop the standard loops into very small slices so complex drum and bass has been in existance since the mid 1990s, but only with the use of computers to aid production has drumfunk taken ahold. Drumfunk is a popular subgenre of Drum and Bass all over the world
Drumfunk focuses on extremely complex drum patterns and simple bass, usually with little or no melody over the top of atmospheric ambient sound effects. It also has very little vocals, and if there are some, it is usually spoken, traditionally taken from films. All these combined give Drumfunk a very “pure” sound, it literally is Drums and Bass.
On a personal note, Drumfunk is fucking awesome.
