Gabber (IPA pronunciation: English /gæ.bər/, Dutch /xɑbər/), gabba or hardcore, is a style of electronic music and a subgenre of hardcore techno. The essence of the gabber sound is a distorted kick sound, overdriven to the point where it becomes clipped into a distorted square wave and makes a recognizably melodic tone. Often the Roland Alpha Juno or the kick from a Roland TR-909 was used to create this sound. Gabber tracks typically include samples and synthesised melodies with the typical tempo ranging from 150 to 220 bpm. Read more on Last.fm.
