Stylized illustration of two women singing to each other passionately on stage, one with a classic rock vibe (50s, leather jacket, tousled hair) inspired by Joan Jett and Katey Sagal, and the other with a modern pop look (20s, bold outfit, short hair) reminiscent of Miley Cyrus and Fletcher. The background is filled with swirling neon lights (electric blue, purple, red), evoking the raw energy of a live performance. The style should blend classic rock poster art with a contemporary digital touch, inspired by Stanley Mouse's bold lines and Alan Aldridge's vibrant colors. --s 250
