From wikipedia:

Hardcore (also known as hardcore techno)^[2][3] is a genre of electronic dance music that originated in the Netherlands, Belgium, and Germany^[4] in the early 1990s. It is distinguished by faster tempos and a distorted sawtooth kick (160 to 200 BPM or more^[5]), the intensity of the kicks and the synthesized bass (in some subgenres),^[6] the rhythm and the atmosphere of the themes (sometimes violent),^[7] the usage of saturation and experimentation close to that of industrial dance music. It would spawn subgenres such as gabber.
