Watch: MEGADETH's DAVE MUSTAINE Lashes Out At JUDAS PRIEST's Crew During BARCELONA ROCK FEST

MEGADETH frontman Dave Mustaine reportedly became irritated when JUDAS PRIEST's road crew began soundchecking while his band was performing at Spain's Barcelona Rock Fest this past Saturday, July 2.

Barcelona Rock Fest is staged at the Parc de Can Zam in Santa Coloma de Gramenet, just twenty minutes from the center of Barcelona. The festival revolves around two identical main stages set up side by side (Stage Rock on the left and Stage Fest on the right). The format is meant to eliminate the classic festival dilemma of having to choose between two bands that are playing at the same time, enabling artists to play almost continuously one after the other throughout the day. While one band is playing on one stage, the crew prepares the other stage for the next act.

After MEGADETH played the sixth song of its set, "Trust", a visibly annoyed Mustaine stopped the show in protest of the crew on the other main stage which was getting ready for PRIEST's performance later in the night.

"We'll wait till he's done checking his guitar over there," Dave said into the microphone.

After a long pause during which he apparently flipped the bird at the crew member in question, Mustaine continued: "The last night of the tour — we went all the way to the last fucking night, and then some pussy over on the stage next to us has to start playing while we're playing. How fucking pathetic, amateur piece of shit you are."

After another brief pause, Dave said: "Can we proceed now?" and then muttered under his breath, "Fucking cunt."

"This is called 'Symphony Of Destruction'," he added before he and his bandmates launched into the song.

The "metalreporterjuso" YouTube channel, which uploaded video of Mustaine's rant, referred to the incident in the clip's description as "Dave having some issues with JUDAS PRIEST crew, lol".

In its review of MEGADETH's performance, Spain's Metal Journal web site wrote (translated from Spanish using Google Translate): "MEGADETH put their great thrash metal card on the table until Dave Mustaine got really pissed off because JUDAS PRIEST's soundcheck bothered him. Then he returned to shine his particular character after uttering a good string of insults. The concert was stopped for a few minutes that became eternal."

MEGADETH will release its sixteenth studio album, "The Sick, The Dying… And The Dead!", on September 2 via UMe. Featuring twelve new tracks, "The Sick, The Dying… And The Dead!" will be made available on CD, vinyl, and cassette, as well as digitally through all online partners. There will also be a limited deluxe edition 2LP, 12-track album pressed on 180g black vinyl housed in a numbered gatefold jacket with a 12x24 lyrics/credits insert, a lenticular vinyl lithograph and a bonus seven-inch featuring "We'll Be Back" and the unreleased B-side "The Conjuring (Live)". The limited deluxe edition can only be purchased via MEGADETH's official online store, through Sound Of Vinyl and uDiscover.

The first song to be released from "The Sick, The Dying… And The Dead!" is "We'll Be Back", which was accompanied by "We'll Be Back: Chapter I", an epic, action-packed short film chronicling the origins of MEGADETH's mascot, Vic Rattlehead. Produced by Mustaine, "We'll Be Back: Chapter I" is a soldier's tale of bravery, personal sacrifice, and the will to survive. It is the first installment of a trilogy of videos to be released in conjunction with the release of "The Sick, The Dying… And The Dead!"

Reuniting Mustaine with co-producer Chris Rakestraw (DANZIG, PARKWAY DRIVE),who together helmed 2016's "Dystopia", "The Sick, The Dying… And The Dead!" was recorded at Mustaine's home studio in Nashville, Tennessee, with guitarist Kiko Loureiro and drummer Dirk Verbeuren. Bassist Steve DiGiorgio temporarily stepped in to record the album. With the kick-off of MEGADETH's recent tour, MEGADETH alumni James LoMenzo rejoined the MEGADETH family as permanent bass player.
