The primitive
description; a drum loop played over a bass line (definition cut down to its utter least).A product of England (mainly London and Bristol) D&B is said to be the most technical form of music of today (with the most complicated drum logarithms/sequences/patterns and loops even heard).
It became big in the 90's with the rave culture.
There are many differing styles, some more slower and ambient forms are common place on tv ad's and commercials, and is often heard in the background.
It is now more known to be a more
intellectual form of
electronic music thats deep and meaningful compared to other forms of (modern dance) music. The faster (140bpm+) style
obviously attracted the club culture, but the more diverse sub-genres can include jazz,reggae,latin,hiphop or samba vibes.
More recent chart D&B success includes DJ Marky & XS, Jaimeson, and Puretone.
The 90's saw the Prodigy with "charly" become a supreme example of DnB.
This genre is still relativley underground, which is probably the best place for it. It can be a rather explicit form of music, that suits the youth of today and their life style.
