Drum an bass (commonly abbreviated to d&b, DnB, dnb, d'n'b, drum n bass, drum & bass) is a type of electronic dance music also known as jungle which emerged in the late 1980s. The genre is characterised by fast tempo broken beat drums (generally between 160–180 beats per minute) with heavy sub basslines. In the 2000s, drum and bass is still considered an underground musical style, but it has nevertheless had a significant influence on popular music and culture.
