Drum and bass (drum n bass, DnB) is an electronic music style. Drum and bass, originally an offshoot of the United Kingdom breakbeat hardcore and rave scene, came into existence when people mixed reggae basslines with sped-up hip hop breakbeats and influences from techno. Pioneers such as raggamuffin DJ General Levy and other DJs quickly became the stars of Drum and bass, then still called jungle. Producers such as Goldie and 4 Hero transformed the current art and turned drum and bass in more instrumental direction, spawning sub-genres like techstep and moving the genre closer to techno. Some of the more popular and defining artists include Shy FX, Ed Rush & Optical, LTJ Bukem, Goldie, and Roni Size.
