Deadbolt / El Vez Weekend
The answer came to me via a hotel key card I accidentally brought home with me.
New credo: When Flequi is unavailable, call upon The Scariest Band in the World.
I secured a bottle of stage blood ("Zesty Mint Flavor") and set out for Southern California, where Deadbolt was to play at Bar Deluxe.

Coincidentally, I was already going to L.A. that weekend to meet up with Bigrig Industries for the El Vez Gospel Show.
