Retro-Roboter-Orchester in goldener Opernhalle

Magnificent art deco opera hall with ornate golden architecture, crimson velvet seats, and crystal chandeliers casting warm amber light. On stage, an ensemble of vintage brass and copper robots with polished chrome details performing classical music. Each robot features intricate mechanical joints, glowing vacuum tube eyes, and articulated metallic fingers gracefully holding instruments - violins, cellos, trumpets, and drums. Dramatic spotlights illuminate the robotic orchestra while creating long shadows across marble floors. Rich burgundy curtains frame the scene. Atmospheric perspective shows ornate balconies filled with soft golden glow. Metropolis-inspired aesthetic with steampunk elegance and theatrical grandeur.
