MEGADETH's main man Dave Mustaine has uploaded a video on Thursday, apologizing to the fans saying that they deserved a much better performance from the band and fully blamed his guitar tech for the less ideal show and said he was a "total waste of skin and life."

Dave Mustaine is definitely not satisfied with how Megadeth's show in Brisbane, Australia went down, but instead of taking it to the whole crew and the whole production team he put the entire blame to his guitar tech and expressed it through a video, which he posted to his Periscope account.

"You deserve way better than this jerk-off did tonight," he said. "Megadeth is much better than what we appeared tonight. But you know what the funny thing is? He has to live with himself. And as of, like, right now, I'll never see his stupid ass again," suggesting that he already fired the guy.

The rocker didn't go into further details on what went wrong and didn't reveal what caused his anger to the technician. All we know is he just expressed his anger on a less than one minute video footage.

MEGADETH's current concert lineup is rounded out by bassist David Ellefson, LAMB OF GOD drummer Chris Adler and Brazilian guitarist Kiko Loureiro, who is best known for his work with ANGRA.

The band's fifteenth studio album, 'Dystopia,' is due to be released on January 22 next year.

Meanwhile, Dave Mustaine is currently writing his second book following the great success of his first book titled 'Mustaine: A Heavy Metal Memoir.' His first book was a huge success considering the fact that it landed at No. 15 in the New York Times' 'Hardcover Nonfiction' category.

However, the book's title and what the book is all about is still a secret, though he revealed that he started writing last summer.
