Liquid dnb (aka liquid funk) supposedly has slight components of funk, according to wikipedia. I guess this explains the more relaxed vibe compared to other dnb music. source: http://en.wikipedia.org/wiki/Liquid_funk

Liquid funk (alternatively, Liquid Drum & Bass or Liquid) is a sub-genre of drum and bass. While it uses similar basslines and bar layouts to other styles, it contains fewer bar-oriented samples and more instrumental layers (both synthesized and natural), harmonies, and ambience, producing a calmer atmosphere directed at both home listeners and nightclub audiences.

Liquid funk has stronger influences from soca, latin, disco, jazz, and funk music...
