"ArcAttack employs a unique DJ set up of their own creation to generate an 'electrifying' audio visual performance. The high voltage DJ pumps music through a PA system while two specially designed DRSSTC's (Dual-Resonant Solid State Tesla Coils) act as separate synchronized instruments. These high tech machines produce an electrical arc similar to a continuous lightning bolt and put out a crisply distorted square wave sound reminiscent of the early days of synthesizers."
