Who would’ve guessed that the heaviest metal show of the spring season would come from three young ladies from Monterrey, Mexico? Fans of The Warning know all too well that the international sensations crush skulls as much as—if not even more than—their older, more established compatriots. (It’s generally regarded that The Warning’s earnest cover of Metallica’s ‘Moth to Flame’ delivers more than the original.) That’s why the metal maniacs at Surly Brewing are sponsoring the show that also includes the dark surreal outlaw country of DEVORA. Weds, 8:30 PM. $18-36.
