And he says that now he's older, he no longer feels the need to sing aggressively - although he did at the start of his career. He tells VH1: "At one point, yes, but I'm 44 years old. I've been doing this band for 21 years. Now on the new record, there's some different stuff on there.

"There's one song where it's almost clean vocals and it's me doing it. That's the most fun I've had in the studio in a long time." Blythe also says there was never a question of the band standing in the way of Chris Adler who has teamed up with Dave Mustaine and co to record Megadeth's follow-up to 2013's Super Collider.
