Portrait 2:3 printed gig poster, full-bleed 1960s-inspired psychedelic screenprint composition for a jam-band concert. Exact rendered copy, all spelling and punctuation must be precise: tiny curved top line "ONE NIGHT ONLY"; dominant two-line headline "KALEIDOSCOPE" / "KINGS"; below headline "LIVE AT THE FILLMORE"; bottom details "FRIDAY · AUGUST 28 · 2026" and "8 PM · SAN FRANCISCO". Build the headline as custom chunky rounded display lettering with thick even strokes, broad soft corners, generous closed counters and tightly controlled spacing. Every glyph is packed with many nested contour bands that precisely follow its silhouette; flat, crisp screenprint ink only, no gradients. Alternate equal-intensity color boundaries: hot magenta/acid green, electric orange/cobalt blue, cadmium yellow/violet, producing visible simultaneous-contrast buzz and fine moire-like optical shimmer. The words KALEIDOSCOPE KINGS occupy 78% of poster width, centered and stacked, with the bands remaining readable at distance. Surround the title with a symmetrical kaleidoscopic field: concentric radiating rainbow rings, four spiraling paisley arms, wavy op-art rays reaching all edges, and small five-petal daisies in the outer corners. Use hard-edged, maximum-saturation flat inks, thin black keylines only where needed for separation; no photorealism, no shadow gradients, no modern UI. Supporting copy is compact custom hand-drawn sans lettering in pale cadmium yellow on deep cobalt-blue curved ribbons, with high legibility. Slight imperfect registration offsets and tactile paper-fiber grain evoke a hand-pulled screenprint. Even high-key backlit-poster illumination, frontal orthographic view, no frame, no mockup, no extra text, no illegible lettering.
