Create a dark, high-contrast poster with a moody, underground club aesthetic. The composition features a monochrome portrait of a young woman 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.
