Along with special guests Trivium and In Flames, Megadeth and Lamb of God will bring the 'Metal Tour of the Year' to North America this summer and fall.

'I want to thank all of you for the support and well wishes these last few months,' said the 'Symphony of Destruction' rocker.

"Unfortunately, this requires that we cancel most shows this year," said the band's frontman and co-founder.

All four of the Prince of Darkness' Canadian gigs will be rescheduled in 2020.

Two members of Megadeth -- including its Canadian drummer -- quit the popular thrash metal band on Tuesday.
