“The most unusual thing for me was being out in Iowa for three months! I’d never been before and it was very dry, very hot, very flat.
"The nice thing about the two guitar players is that their styles are so different and yet complementary. Josh [Rand] is very methodical. He had pages and pages of scales he wanted to try soloing on. It was very thought out, considered and practiced.
"Jim [Root] is fly by the seat of his pants. What he plays is amazing but he can’t do it again! Both fantastic guitar players. It’s not one guy trying to copy what the other guy is doing - they bring different colours and it’s that kind of Lennon/McCartney thing. They make it unique because one pulls the other in different directions.
"Corey then comes in with a great story over the top. With that huge neck of his, he pumps it out. I heard from some people saying his singing was on fire. That makes me happy because I work hard to get the best out of singers.
“They were hands-on in getting the tones as we were playing. Jim was saying it was the happiest they’d ever been with their guitar tones. But they had been so busy with Slipknot that the writing of the record was a lot more fractured and we really pulled it together in the studio I think.
"There are a couple of songs we got Corey to re-write as we were in the studio and they worked out really well. They had ideas but I think they were looking to me a little more on the production side to push them in a certain direction, staying within the framework of rock, metal and what they do. It’s a great quality record and the songs are amazing. It should do very well. Like I said, I’m the eternal optimist!”
