Robert Kovacic is known as drummer in Scaffold, Supreme Pain (both death metal), and Crossroatsz (an ondustrial/hardcore/metal band). He is also available as drum teacher and session musician.



Robert Kovacic also sat behind the kit for Austrian extreme metallers Belphegor on their "Pestapokalypse VI" tour as session drummer.



In June 2008 Robert Kovacic departed Dutch brutal death metal band Supreme Pain. According to the remaining band members Robert had a busy schedule as a session drummer and therefore not much time left for Supreme Pain.
