Create a vintage 1969 psychedelic concert poster in a Wes Wilson-inspired San Francisco rock-poster style, printed on aged folded paper with scuffs, creases, faded ink, and a tan border. The composition is a square poster with a deep purple background filled with subtle swirling paisley waves, enclosed by an irregular black vine-and-tendril frame with neon green highlights. At the top, huge warped melting hand-lettered headline text reads {argument name="band name" default="COSMIC DRIFT"}, in orange-to-hot-pink gradients with black shadowing and green outline, stretched and distorted into organic bulbous letterforms. Beneath and around the title are 6 distinct event text elements: “performing LIVE at THE ELECTRIC OWL BALLROOM”, “JUNE 21 1969”, “SAN FRANCISCO 777 GROOVE ST AT THIRD”, “with VELVET HAZE and”, “THE BURNING MONKS”, and a tiny footer reading “TICKETS $3.50 • DOORS 8PM • BROUGHT TO YOU BY THE HAIGHT INDEPENDENT SOUND SOCIETY”. The central art shows a black silhouette of a long-haired electric guitarist leaning backward in a dramatic rock pose, one arm raised, guitar neck angled upward. Behind the performer, make a radiant orange, lime green, yellow, and magenta burst of psychedelic rays, wavy stripes, and liquid shapes. In the upper right of the burst, place a giant surreal eyeball-sun with red veins, a hypnotic spiral pupil, rainbow rays, and dripping goo hanging from the lower edge. Add exactly 7 smaller floating spiral-eye discs across the burst, plus a few tiny planets, mushrooms, bubbles, stars, flowers, flames, and abstract 1960s counterculture doodles. Use saturated fluorescent colors: {argument name="primary poster colors" default="purple, hot pink, orange, lime green, yellow, and black"}. Make the typography dense, hand-drawn, highly ornamental, legible but wavy and hallucinatory, with authentic screen-printed texture and slight misregistration. Copy prompt
