Drum & bass — abbreviated D&B or DnB — is a fast, breakbeat-driven UK genre that grew out of the early-1990s rave and jungle scenes. The style is built on chopped breakbeats (most famously the Amen break), heavy sub-bass, and tempos of 165–175 BPM. As jungle splintered in the mid-1990s, D&B emerged as the smoother, more techno-leaning offshoot. Subgenres include liquid funk (warm, jazz-influenced), neurofunk (dark, technical), jump-up (fun, riff-driven), and minimal/halftime (atmospheric). The UK remains the genre's commercial centre — Hospital Records, Ram Records, and UKF dominate the streaming side — while the global circuit runs through events like Let It Roll (Czech Republic), Rampage (Belgium), and Hospitality.
