Earlier this month, Megadeth canceled most of its 2019 dates—including a scheduled performance at Psycho Las Vegas—with the announcement that frontman Dave Mustaine had been diagnosed with throat cancer.

Today, the festival—set for August 16-18 at Mandalay Bay Events Center—revealed its replacement Saturday-night headliner: New Jersey horror-punk godfathers The Original Misfits, who have played only a handful of shows since reuniting with original frontman Glenn Danzig in 2016.

Those concerts—including a December 2017 stop at Las Vegas’ MGM Grand Garden Arena—have featured a lineup of Danzig and founding bassist Jerry Only along with early guitarist Doyle Wolfgang von Frankenstein and new arrivals Dave Lombardo (drums) and Acey Slade (rhythm guitar). Danzig played Psycho Las Vegas 2018 with his eponymous post-Misfits band, performing 1992’s Danzig III: How the Gods Kill in its entirety.

The Original Misfits join a loaded Psycho lineup that includes headliners Electric Wizard (Friday) and Opeth (Sunday), plus Godspeed You! Black Emperor, Beach House, Uncle Acid & The Deadbeats, Clutch, High on Fire, Mogwai, Graveyard, Bad Religion, Carcass, The Faint, The Black Angels, Rotting Christ, Deafheaven and many more.

Psycho Las Vegas, which took place at the Hard Rock Hotel in 2016, 2017 and 2018, will begin its run at Mandalay Bay with a Psycho Swim pool party—featuring such acts as Corrosion of Comformity, Lucifer and Danava—on Thursday, August 15. The main festival will utilize four stages at the south-Strip resort: Mandalay Bay Events Center, House of Blues, Mandalay Bay Beach and Rhythm & Riffs Lounge.

Psycho tickets cost $249 for the weekend or $109 per day and are on sale now at vivapsycho.com.
