Vinyl Turntable Groove City Poster

Create a 4:5 vertical vinyl turntable promotional poster. The core composition is 'Groove Sound City'. Use a direct overhead shot. A minimalist square turntable occupies about 60% of the bottom of the frame, with a body of dark walnut and matte black metal. The vinyl record is spinning, the tonearm structure is accurate, and the needle truly contacts the record grooves. The six concentric grooves in the upper half of the record gradually lift off the disc surface, transforming into six black curved walls with real height. The curved walls are arranged from low to high along the rotation direction. Each wall top has extremely thin electric blue frequency textures; between the walls, an abstract ring-shaped sound city is formed. The grooves must remain concentric with the record center and cannot become arbitrary waves or equalizer bar charts. The title 'SPIN' is arranged outward from the record center along four sectors. Each letter lies flat on the disc surface, slightly elongated according to perspective and rotation direction; the tonearm grazes past the outside of the letter N without blocking it. Leave a large area of warm gray negative space at the top of the frame, placing only small text 'ANALOG TURNTABLE' and a short sentence 'THE GROOVE BECOMES SPACE'. Use hard light from the upper side to produce clear and slender ring wall shadows, and use soft ambient light to preserve wood grain and metal details. Color scheme is matte black, dark walnut, warm gray, and a touch of electric blue. Complete opaque rectangular background, no transparent pixels, no black corners, no alpha masks, no edge feathering. No human arms, no DJ stages, no neon bars, no dense audio UIs, no existing brand logos, no watermarks.
