For the most anticipated weekend of the year, Cityfox erects its annual playground for Halloween’s saints and sinners (though let’s be honest, it caters to sinners). With 14-plus stages and live acts, zombie-like partygoers will be wandering Brooklyn’s massive Avant Gardner warehouse in a trance, moving through swarms of extravagant outfits both glitzy and horrific, and swaying to headlining D.J. Lee Burridge’s tribal tunes. This Halloween festival is predictably, well, unpredictable. —E.C.
