Megadeth have been working on their 15th studio album in Nashville, Tenn. In a new interview with Guitar World, frontman Dave Mustaine talks about the record, new guitarist Kiko Loureiro and other subjects.

After the exit of guitarist Chris Broderick and drummer Shawn Drover and rumors of reunions with former members, Megadeth brought aboard Lamb of God‘s Chris Adler to play drums on the album and recruited Angra's Kiko Loureiro to be one of their guitarists. Mustaine has already raved about Loureiro, calling him the "best guitarist we've ever had."

Mustaine says he and Loureiro get along well. “Chris and I had a good chemistry, but we weren’t really as close as I would have wanted us to be,” Mustaine says. “Kiko, I feel like I’ve known him for years.”

As to the sound and lyrical content of the new album, Mustaine says, “There’s nothing too out of the ordinary on the record. I think probably the most noticeable thing will be how my playing with the San Diego Symphony [in April 2014] affected some of my guitar work. Learning Vivaldi and Bach and all that, there’s some stuff on the album where you can tell that made an impression on me."

Mustaine continues, “But, there’s nothing like ‘Blackest Crow’ [from Super Collider], and, lyrically, nothing like songs that were on Risk, talking about ecstasy or the breadline and stuff like that. These songs are definitely very dark. But is there anything unexpected? It depends what you expect. And anyway, to be predictably unpredictable…is still to be predictable.”
