Gabber

Gabber, gabba, (/ˈɡæbər/; from Dutch: [ˈxɑbər]), Rotterdam techno, Rotterdam hardcore or retrospectively called early hardcore, is a style of electronic music and a subgenre of hardcore.

Although a house variant from Detroit, Gabber music reached Amsterdam in the late 1980s, it was the producers and DJs from Rotterdam in the early 1990s who evolved it into a harder house variant which is today known as "gabber".
