UnicaZürn's core instrumentation blends analogue synthesiser, mellotron and electric piano with electric guitar and saxophone. Knight is reknowned for his pioneering multi-textured fretwork with Danielle Dax and Shock-Headed Peters, and his ambient guitar settings for Lydia Lunch, while Thrower's reed playing provided rage and melancholy in Coil and turns to electro-acoustic texture in Cyclobe.
