MEGADETH frontman Dave Mustaine recently penned an original song, 'Sudden Death', specifically for the forthcoming Guitar Hero: Warriors Of Rock game.

The track can now be heard in a new demo from IGN. Check it out below:

Mustaine recently spoke with Chris Harris at Rolling Stone about 'Sudden Death'. An excerpt from the article is available below:

'Sudden Death' turned into a scathing, speedy thrash tune that's sure to lead to some fingertip callusing. Mustaine claims the song has a "funky kind of polyrhythm to it" which will make it even more difficult for the Guitar Hero elite. "Just the sheer repetitiveness of it can blow people's minds," Mustaine explains. "And, my guitar style is way different than [other Megadeth guitarist] Chris Brodericks'. Chris plays with a lot of love and I play with a lot of hate. My guitar playing is explosions, and his is more like fireworks. When you are trying to emulate the two kind of guitar styles, it's tricky. I don't care what anyone says, you've gotta be good."

Due out this fall, Guitar Hero: Warriors of Rock isn't the only excitement on Mustaine's plate these days. With bassist Dave Ellefson back in the equation, there's pressure from fans for new music. Meanwhile, Megadeth will be heading overseas this summer to play with the rest of the "Big Four" of thrash (Metallica, Slayer and Anthrax) at festivals, marking the first time all four bands have shared the same stage. As Rolling Stone reported, one of the gigs will be broadcast live in movie theaters around the globe. Megadeth is also fresh from playing Rust in Peace on their last tour with TESTAMENT and EXODUS, and will hit the road this summer with SLAYER and Testament for the "American Carnage" trek.

Mustaine's not thrilled that the "Big Four" tour isn't a global undertaking, and thinks American fans "deserve it as much as anybody does." So, does he see it coming stateside? "Of course it could happen. I don't know that it will. I hope it does," he says. "If we could, I know we would. It's just a matter of the degree of touring availability for the other parties concerned. Let's be honest about all this: The cards lay in one camp's hands and the rest of us are just damn happy to be here."
