Update – February 13th 11:55am:
Dave Mustaine has since commented to a fan on the matter, you can find his response here.
Megadeth‘s ‘Best Metal Performance’ Grammy win today, February 12th, wasn’t without a bit of irony as a rendition of Metallica‘s “Master Of Puppets” played as the band walked the aisle to accept the award. Vocalist/guitarist Dave Mustaine seemed to take it all in stride, riffing along as they walked to the stage. You can watch footage of that below. Mustaine himself in the past has of course had a complicated relationship with Metallica after being ejected from the lineup early in their career.
