While trickling out many of the acts in its 2019 lineup over the past few months—Beach House, Bad Religion, Godspeed You! Black Emperor and The Faint among them—Psycho Las Vegas signaled that this year’s festival would feature a wider sonic spectrum than its three predecessors.

Never fear, metalheads. On Thursday, when the fest revealed its full bill, the three headliner spots were occupied by more traditionally heavy bands: longtime LA thrash veterans Megadeth, Swedish prog favorites Opeth and previously announced doom titans Electric Wizard (who also anchored Psycho’s first Vegas edition in 2016).

Also on the lineup for the August 16-18 event, which moves to Mandalay Bay from the Hard Rock Hotel this year, are Clutch, High on Fire, Mogwai, The Black Angels, Mark Lanegan, Uncle Acid & The Deadbeats, Graveyard, Deafheaven, Glassjaw, Cold Cave, Fu Manchu, Triumph of Death, Carcass, Rotting Christ, Power Trip, 1349, Old Man Gloom, The Crazy World of Arthur Brown, Tobacco, Dead Meadow, Oranssi Pazuzu, YOB, Black Mountain, Full of Hell, Goatwhore, The Obsessed, En Minor, Kadavar, Amenra, Nothing, Perturbator, Soft Kill, Vio-lence, Truckfighters, Dvne, Grails, Have a Nice Life, Yakuza, Mork, Royal Thunder, Warhorse, Hangman’s Chair, L.A. Witch, Spindrift, Twin Temple, Ilsa, Devil Master, Night Horse, Tomb Mold, Monophonics, Polyrhythmics, Electric Citizen, Led Zeppelin II, Motorbabe, Candy, Levitation Room, Hellfire, Mother Mercury, Two Minutes to Late Night and Andrew W.K., scheduled to spin a DJ set to close out the weekend.
