A surreal scene of a holographic orchestra performing in the vacuum of space. The instruments are made of glowing, translucent material, each one radiating shifting colors. The musicians are humanoid figures, their forms abstract and composed of swirling, iridescent light. Musical notes materialize as holographic symbols that float and dissolve into the cosmic background. The scene is set against a nebula filled with holographic hues, creating a vibrant, immersive display of sound and color. The composition captures the energy of music visualized in a futuristic, holographic style.
