Dark high-contrast poster with moody underground club aesthetic

Create a dark, high‑contrast poster with a moody, underground club aesthetic. The composition features a monochrome portrait of Elon Musk from the chest up, shot from a slightly low angle for attitude and power. She wears large over‑ear headphones and reflective round sunglasses with warm amber‑gold lenses that stand out vividly against the black‑and‑white portrait. One hand is raised near her head, the other near her chin, creating a dynamic, expressive pose associated with music immersion. Behind her head is a large flat golden‑yellow circular shape, like a spotlight, creating a strong focal point and visual contrast. The background is deep black with subtle grunge textures, dust, scratches, and poster‑wear imperfections, giving it a raw, printed‑flyer feel. Use 4:5 aspect ratio.
