A future music festival held under the vast Milky Way, set on a huge transparent platform suspended in the air, surrounded by flowing nebulae and scattered planets. The stage design adopts high-tech holographic technology, with a dynamically changing three-dimensional light screen in the center. As the notes jump, they transform into psychedelic geometric patterns and dazzling flowing light, sometimes with jumping sound waves and sometimes transforming into a dreamy image of a virtual singer. The audience comes from all over the galaxy, dressed in various bizarre costumes, some dancing in the air in anti gravity shoes, and some hovering in personal flying machines to watch the performance. Their attire blends retro and futurism, wearing LED outfits on their heads
