You're not sure how it got there, but there is also a flyer near the door to the Electric hellfire:

Auditions will be held tonight at the Neon Burn. The lead singer from Morituri is looking for a new band. Metalheads of all varieties welcome, as long as they can play fucking fast! Starts at 9:00 pm. Bring your kinks, have drinks, play some fucking metal!

This flyer has a hand-drawn picture of the Devil laughing in an electric chair,l signed Nikki.
