Stylized illustration of two women performing on stage, one in her 50s with a classic rock look (leather jacket, tousled hair), and the other in her 20s with a bold modern style (bright outfit, short hair). They are singing together on a stage under glowing spotlights, surrounded by a crowd with their hands up. The illustration should use bright neon colors (electric blue, purple, and red) to evoke the raw energy of a live performance. The style should be reminiscent of a mix between modern pop art and classic rock poster aesthetics, by an artist like Stanley Mouse or Alan Aldridge. --s 250
