Nu skool breaks (or nu breaks as it is sometimes referred) is a subgenre of breakbeat originating during the period between 1998 and 2002. The style is usually characterized by more abstract, more technical sounds, sometimes incorporated from other genres of electronic dance music, including UK garage, electro, and drum and bass. Typically, tracks ranged between 125 and 140 beats per minute (bpm), often featuring a dominant bass line. In contrast with big beat, another subgenre of breakbeat, the sound set consisted less of hip hop samples and acid-type sounds, instead emphasizing dance-friendliness and "new" sound produced by modern production techniques using synthesizers, effect processors, and computers.
