An illustration of two women on stage, facing each other holding hands as if about to sing a duet. 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 background blends retro textures with neon concert lighting, using contrasting colors (deep blue and bright pink) to symbolize the mix of old and new. The art style should evoke classic rock posters with a contemporary twist, reminiscent of the work of Wes Wilson.  --stylize 800 --ar 1:1
