ABC Diabolo were a German Metalcore band from the early to mid-90s. Their style was Rorschach-ian. Lyrics dealt with political issues. ABD Diabolo probably could be considered one of the pioneers of German metalcore which became an outfit in the later 90s, while never gaining the status of scene superstars. The band released their records on DIY label Common Cause Records who also put out early Dawnbreed (pre-Monochrome) and Berlin based Ambush both pioneering a more eclectic hardcore style.
