For more than three decades, the Misfits—the godfathers of the horror-punk genre—have seen their music covered by dozens of punk bands, as well as a trio of Rock and Roll Hall of Famers: Metallica, Green Day and Guns N’ Roses. But here’s the thing about imitation: It ain’t the real deal. And given that the Misfits’ founding members hadn’t shared a stage since Michael Jackson’s Thriller was topping the charts, it seemed more likely that the band’s fans (Fiends, as they’re known) had a better chance of seeing a zombie apocalypse than a reunion of singer Glenn Danzig, bassist Jerry Only and guitarist Doyle (who is Only’s brother). Then early in 2016, a funny thing happened while Danzig and Jerry—at odds for decades—engaged in yet another legal tussle: They buried the hatchet and agreed to perform together for the first time in 33 years. Alas, after two wildly successful concerts at last fall’s Riot Fest, the Misfits vanished, leaving all to wonder if the original lineup would ever again be resurrected. Indeed, it will: Reunion show No. 3 lands in Las Vegas this week. Happy belated Halloween, Fiends!
