Although rooted in hardcore techno, Drum 'n' Bass (or Jungle music) has evolved steadily since the early 1990s, and although much of the music remains rhythmically complex, the genre has been successfully assimilated into mainstream culture as it broadens its outlook, incorporating aspects of jazz, film music, ambient, and trip-hop. UK Garage adds elements of raga, DJ scratching and diva vocals to produce a uniquely British (and hugely successful) offshoot.
