Megadeth frontman Dave Mustaine has revealed that hand troubles are forcing the band's farewell tour. "I don't wanna go out in front of our fans and not be able to do my best." He pointed out that thrash metal is "a young man's game" where some musicians keep burning bright while others shift direction. Plus, thrash metal is very fast, so it can be more difficult to play as players get older over the years. For the latter album, Megadeth won a GRAMMY for the record's title track.
