A twisted psychedelic concert poster for a dark interstellar music show. Featuring band names: Squall, Starlab Arcada, Doomgazer, Eccentric Bird Things. Styles: stoner punk, doom drone, progressive metal, experimental noise. Scene: an alien landscape under a swirling black hole sky, with tentacled space gods emerging from dying stars. Ancient, crumbling temples float in space, carved with screaming faces and distorted runes. Giant mechanical bird creatures with fractured wings soar through clouds of electric fog. Amplifiers ooze slime, guitars built from bones and wires pulse with energy. Fonts are warped, melted, dripping, 70s rock poster style but corrupted by cosmic decay. Color palette: neon purples, toxic greens, deep reds, void black. Mood: chaotic, heavy, otherworldly, evil yet hypnotic. Designed in the style of vintage rock posters, fused with cosmic horror and surrealism. See more
