Yet another band has been confirmed to support Megadeth on this year's Gigantour. The fall trek now has four bands locked in, with Hellyeah having been announced over the weekend.

This year's Gigantour will be the fifth installment of the traveling fest, and Megadeth frontman Dave Mustaine has continued the tradition of hand-picking each act. So far, Mustaine has tapped Disturbed vocalist Dave Draiman's new project Device for this year's bill, along with Hollywood rock / metal act Death Division. Adding Megadeth into the mix, we've got four confirmed bands for Gigantour now that Hellyeah have been added.

Hellyeah announced the news on their official Facebook page, declaring, "It's on Hellions, help spread the word!!!!"

Megadeth's 2013 album, 'Super Collider,' is set for release on June 4. The band has already introduced us to a preview of the song 'Don't Turn Your Back' along with the full audio of the album's title track. David Draiman was invited to collaborate with Megadeth for 'Super Collider,' with the Disturbed / Device singer lending his voice to the tracks 'Forget to Remember' and 'Dance in the Rain.' Dave Mustaine was so pleased with Draiman's contributions to 'Super Collider,' that the Megadeth frontman invited Device onto the 2013 Gigantour bill.

A full 2013 Gigantour announcement is expected very shortly. Stay tuned for more details.
