Dave Mustaine decided to steer away from topical subjects and focus more on matters of the heart for Megadeth’s new album, Super Collider. Speaking to Billboard, the veteran guitarist said he deliberately avoided material that might stir controversy.

“[The focus was] a little bit more about human politics this time, like my mother-in-law having Alzheimer’s and things like that,” Mustaine explained. “Not everybody watches the news, so when you tell somebody that this is going on, that's going on, this guy’s part of a cover-up, this guy is a philanderer, they don't want to hear it. But if you say, 'Hey, my mother-in-law has Alzheimer’s,’ or something they might have going on in their life, too, all of a sudden you've got that bond. So I figured I would write about what goes on inside my heart instead of inside my head this time …."

Super Collider debuted at #6 on the Billboard 200, the band’s strongest chart-showing since 1994’s Youthanasia. Megadeth will launch their Gigantour on July 3 in Gilford, New Hampshire, along with fellow metal bands Black Label Society, Device, Hellyeah, Newsted and Death Division.
