Psychedelic Concert Poster

Create a square 1960s psychedelic concert poster in a Wes Wilson-inspired San Francisco rock poster style, with dense hand-drawn warped typography, high-contrast screenprint texture, rough ink grain, and a dark navy background. The headline at the very top should read {argument name="band name" default="COSMIC DRIFT"} in huge hot-pink melting bubble letters that stretch across the width and curl into spiral terminals. Center the composition on a black silhouette of a curly-haired guitarist in a dramatic bent-knee pose, holding an electric guitar, set in front of a giant orange-yellow melting eyeball sun with a green iris and red vein details; add orange flame-like waves radiating from both sides. Include exactly 6 distinct text blocks: 1) top headline "COSMIC DRIFT", 2) left venue location block "LIVE IN SAN FRANCISCO", 3) right date block "SATURDAY JUNE 21 1969", 4) small central block "AT THE", 5) large lower venue block "ELECTRIC OWL BALLROOM SAN FRANCISCO", and 6) bottom supporting act banner "WITH VELVET HAZE AND THE BURNING MONKS". Use saturated hot pink, burnt orange, acid green, mustard yellow, and deep indigo, with ornate vine-like flourishes, swirling borders, paisley corners, and tightly packed negative space. Make the lettering intentionally wavy, distorted, and hand-rendered but still mostly readable, like a vintage 1969 concert bill printed on slightly worn paper. The venue should be {argument name="venue name" default="The Electric Owl Ballroom"}, the city should be {argument name="city" default="San Francisco"}, the date should be {argument name="concert date" default="Saturday June 21 1969"}, and the supporting acts should be {argument name="supporting acts" default="Velvet Haze and The Burning Monks"}.
