YASS # 3 is a German noise-rock band out of the dark woods of the Black Forest. Markus (TEN VOLT SHOCK) and Frank (KURT, TEN VOLT SHOCK) are combining their driving-blistering guitar sound and their heavy pounding beats with dark and pulsating synthesizer-loops to an energetic and powerful piece of modern Noise-Rock.
