"Design an album cover in the style of Kingsway Music Library, evoking a dark, mysterious atmosphere. Incorporate rich textures, muted tones, deep blacks, and shades of gray with subtle accents of crimson or dark purple. Include faint vintage elements like distressed patterns or faded overlays. The title 'Shadow Pack' should be displayed in bold, minimalist typography, slightly weathered or textured to match the ominous mood. Add abstract shadows or silhouettes to emphasize depth and intrigue, ensuring the overall composition feels cinematic and hauntingly beautiful."
