Megadeth will headline the Gigantour and frontman Dave Mustaine has selected Zakk Wylde's Black Label Society, former Metallica bass player Jason Newsted's new solo band Newsted, Hellyeah, Disturbed frontman David Draiman's new band Device, and Death Division which features Hellyeah / Nothingface's Jerry Montano and Morbid Angel / Divine Heresy's Tim Yeung.

The trek is set to kick off on July 3rd at Meadowbrook in Gilford, NH and will conclude over a month later on August 11th at the Molson Canadian Amphitheatre in Toronto.

"This year's power-packed lineup is probably the best Gigantour yet, and we've had some pretty massive Gigantours over the years," Mustaine said in the announcement. "Gigantour 2013 brings four of my favorite bands, each centered around a superstar. With Zakk, David, Vinnie, and Jason there are going to be fans from Ozzy to Disturbed to Pantera to Metallica and everything that's metal in-between! Don't miss the metal festival of the summer!"

Megadeth will follow the trek by joining Black Sabbath's South American tour this fall where they will be performing with the metal legends at four concerts.
