Illustration of two women holding hands on stage, with one looking like a seasoned rocker (50s, leather jacket, flowing hair) and the other with a fresh, modern pop star style (20s, edgy haircut, colorful clothes). The stage is filled with bright neon lights (electric blue, pink, purple), swirling patterns, and abstract sound waves, symbolizing the fusion of rock and pop. The art style should be inspired by psychedelic rock posters with a contemporary twist, similar to the works of Wes Wilson or Stanley Mouse.  --stylize 800 --ar 1:1
