Update: Okay, so by now you've figured out who's playing the secret show at the Fox on Thursday night. If you haven't, well, click through to hear it straight from the horse's mouth.
Checked the Fox Theatre's website lately? Notice anything special happening on Thursday night?The Juarez Street Fighters are playing. So? Uh-huh. Ever heard of 'em? Right. Neither have we. And yet, somehow, they're headlining the Fox? No big. It's happened before. Little known band plays the Fox before everyone else really knows about them. What of it?
Fair enough. What about the listed openers? Fancy's Showbox? Ember? Ever heard of them? Hmm... now those names ring a bell, don't they. But why? Hint: Those are the names of the previous bands fronted by two guys who went on to form one of the biggest bands to ever come out of these parts. Still haven't found what you're looking for? (It's NOT U2, but this is definitely another clue.) Check the artwork on the Fox's website.
