Berlin Techno Club Night Poster

A brutalist Berlin techno club poster, A2 portrait format, almost entirely matte black with a single high-contrast image: a close-up macro photograph of a sweating concrete wall lit by a hard sodium-orange spotlight from camera right, casting a long diagonal shadow across raw rebar marks. The only overlay is razor-thin off-white Helvetica Bold type, set flush-left and rotated 90 degrees along the spine, reading "SCHWARZRAUM // 04.11 // 23:00 - OPEN END // FLOOR A: ANJA HAERTL FLOOR B: KESSEL TRIO". A second cluster of micro-type bottom-right reads "NO PHONES. NO CAMERAS. ID REQUIRED.". A small white circle the size of a coin in the upper-right corner contains the number "017" — the issue number of an ongoing poster series. Subtle 35mm film grain throughout, deep blacks crushed but not solid. The composition is asymmetric, cold, and intentionally austere — no illustration, no people, just architecture, light, and typography.
