Psycho Las Vegas 2017 – set to take place from August 18th through August 20th, 2017 with a pre-party August 17th at the Hard Rock Hotel And Casino Las Vegas in Las Vegas, Nevada – confirms Mastodon as its final remaining headliner.

For over 15 years, Mastodon have set the course for an entire generation of metal that’s progressive and still unbridled in its heaviness. This August, they’ll take their rightful place among the headliners at Psycho Las Vegas.

The Atlanta-based giants arrive on the Psycho Las Vegas bill in the righteous company of the legendary King Diamond, who’ll perform the Abigail album in its entirety as a US-exclusive show for 2017, as well as post-metal forebears Neurosis, the resurgent Corrosion Of Conformity, and countless others over the course of the three-day weekend. It is already – and rightly so – being hailed as one of the best heavy lineups ever put together for an American festival.

Adding Mastodon to that mix only makes it stronger. With genre landmarks like Remission, Leviathan, and Crack The Skye in their catalog, they stand among the most pivotal acts of their era. Their latest offering is the newly-issued Emperor Of Sand, and it reaffirms their commitment to the thoughtful, winding, and furious riffing that has made them a household name among fans and imitators the world over.

Last year, Dig Boston lauded Psycho Las Vegas for boasting, “one of the most amazing festival lineups,” to date. BrooklynVegan praised an event that was both, “fun [and] weird,” with a sound quality that was, “absolutely top-level,” while Las Vegas Review Journal celebrated the festival’s, “communal, come-as-you-are vibe,” furthering, “the whole weekend had the feel of a heavy-metal family gathering meets The Big Lebowski; a laid-back get-together with an ensemble cast of far-out characters, from gray-haired dudes in Captain Beefheart T-shirts to Yeti-shaggy heavy-metal epicureans…” Noisey concurred hailing Psycho Las Vegas for fulfilling, “every hesher’s fantasy of wandering around the Hard Rock Hotel And Casino stoned out of your mind while alternating between gambling, getting wasted, smoking cigarettes indoors, eating Mexican food, flaunting tattoos, and, of course, watching a seemingly endless onslaught of metal bands perform.”

And this year, Psycho Las Vegas will only up the proverbial ante with exclusive 2017 US appearances by French progressive rock unit Magma, black metallers Abbath led by former Immortal guitarist/vocalist Abbath Doom Occulta, and cult stoner/desert rock unit Slo Burn, fronted by Kyuss’ John Garcia. Additionally, Mulatu Astatke, the father of Ethio-jazz, will be making his west of Chicago exclusive appearance while Manilla Road, who are celebrating their 40th anniversary, will perform their classic Crystal Logic in its entirety as a worldwide exclusive for Psycho Las Vegas.
