d&b audiotechnik's Serge Gräfe work as a sound technician was shaped by years as FoH engineer FOR Kraftwerk, where performances demand strict precision and zero tolerance for drift. His role focuses on signal integrity, controlled balance of sparse electronic textures, and keeping interlinked systems stable under tour pressure. Gräfe operates within technical and experimental music spaces that value process over exposure. He prefers close collaboration with performers, embedding himself in the mechanics of a show rather than hovering above it. His approach leans toward control, repetition, and an awareness of how sound behaves physically in a room.
