Wanted Style Poster for Festival

I'm in need of a 'Wanted' style poster for an event I'm advertising. The event is a concert/festival, and I'm looking for a design that captures a dark and mysterious tone. This needs to contrast with the nature of the event itself, adding an edge of intrigue and suspense.

Ideal Skills:
- Graphic Design
- Experience with Event Promotion Materials
- Understanding of 'Wanted' Aesthetic
- Ability to Convey Tone through Design
