Holographic Sound Arena

Create a premium high-end 3D music and entertainment campaign showing a futuristic empty performance arena shaped by enormous luminous sound waves. Use a wide stage camera view from audience height in a vertical 4:5 composition, with the stage centered at dramatic scale. Build the environment from translucent sculptural ribbons, suspended acoustic forms, atmospheric depth, and light haze. Use magenta, ultraviolet, electric blue, and deep black. Render translucent acrylic, holographic glass, a glossy black stage, emissive light structures, concert-grade beams, and volumetric glow. No performers, audience faces, branded instruments, brand name, logo, watermark, visible text, letters, UI, or border.
