The visual style is modern performance posters and high-end concert visuals, featuring the feel of art museum posters, magazine layouts, and a series design language.

The background uses [background color] paper texture, with slight grain, printed texture, and soft blank space; do not use a pure blank background.

Focus on [material characteristics], such as metal reflectivity, wood grain, black lacquer, strings, keys, and curved structures.

DATE / [Date]
VENUE / [Location]
SERIES / [Series Information]

[Program Type]
