Speedcore

Speedcore is a form of electronic music that is characterized by a high tempo and aggressive themes.

[3] Aside from the very fast tempo, speedcore can often be distinguished from other forms of hardcore by an aggressive and overridden electronic percussion track that is often punctuated with a hyperactive snare or tom-tom fills.

[4] Speedcore DJs often use violent, vulgar, and offensive themes in their music to push the boundaries of the genre.

[5] Since the 2000s, the use of digital audio workstations (DAWs) has grown versus the use of analog synthesizers or trackers.

[4] Belgian artist DJ Einrich refined the sound in the late 1990s, using oscillators to transform fast kick drums into notes in octaves.

Speedcore was no longer restrained to localized areas where raves occurred and records were released.
