Breakcore is a style and microgenre of electronic dance music that emerged from jungle, hardcore, and drum and bass in the mid-to-late 1990s. It is characterized by very complex and intricate breakbeats and a wide palette of sampling sources played at high tempos.

Hardcore is a genre of electronic dance music that originated in the Netherlands, Belgium, and Germany in the early 1990s. It is distinguished by faster tempos and a distorted sawtooth kick, the intensity of the kicks and the synthesized bass, the rhythm and the atmosphere of the themes, the usage of saturation and experimentation close to that of industrial dance music. It would spawn subgenres such as gabber.
