A dynamic illustration of two women performing together on a stage, one representing the rock legends of the past (50s, band t-shirt, ripped jeans, inspired by Katey Sagal) and the other embodying contemporary pop/rock (20s, flashy outfit, statement jewelry, inspired by Fletcher). The background blends retro concert visuals with abstract, glowing neon lights (electric blue, magenta, and yellow), capturing the fusion of different musical generations. The style should combine the boldness of classic rock posters with modern pop art influences.  --stylize 850 --ar 1:1
