ドラムンベース
Drum and bass (also written as Drum&amp;Bass or drum'n'bass and commonly abbreviated as D&amp;B, DnB, or D'n'B) is a genre of electronic music characterised by fast breakbeats (typically 165-185 beats per minute) with heavy bass and sub-bass lines, samples, and synthesizers. The genre grew out of the UK's jungle scene in the early 1990s.
