Illustration of two women on stage facing each other, holding microphones. One is styled as a seasoned rock star (50s, leather pants, flowing top, inspired by Stevie Nicks), while the other embodies modern pop energy (20s, edgy outfit, vibrant hair, similar to Sasha Sokol). The background features a blend of vintage concert textures with glowing neon elements (electric blue, magenta, and gold). The style should evoke the feel of 70s rock posters, updated with a modern digital art twist, focusing on the mix of the two eras and personalities.  --stylize 750 --ar 1:1
