Speaking to Let There Be Talk podcast, Slipknot and Stone Sour frontman Corey Taylor has revealed what he learned from producer Greg Fidelman.

Here’s the statement:

“I have learned from the Ross Robinson school of production. I loved it. Absolutely. It’s, like, there’s a reason I’m working with him — it’s because I can’t do it on my own.

I wanna learn, I want a challenge — I want that. When it came time to work with Rick, he just wasn’t fucking there. He had six different projects going on, it felt like. It’s, like, ‘Oh, I’m working with U2 now.’ And I’m, like, ‘We’re still in the fucking studio, dude.’ Honestly, it wasn’t until we finished the vocals at his house that I saw him more than once a week.

I won’t get into the nuts and bolts of my issues, but we got a great album out of it — one that is hard for me to listen to. Because that was the album where I really started to get sober.

So there’s a lot of that I can’t listen to. However, Greg, to me, was the best takeaway from that experience — working with Greg, and then getting to know Greg. And then Greg has gone on to do fucking everything, man. He’s produced Metallica… He does so much with so many people. The proof’s in the pudding.

Greg knows how to think for himself. He’s learned some stuff from Rick, but at the same time, there are a lot of people who have worked with Rick who haven’t gone on to have the kind of career that Fidelman had… So [Fidelman is a guy] that [has] my total respect because [he] learned how to do it, but [he] go down that wormhole.”

According to Wikipedia, Greg Fidelman worked with many bands in various genres, many in the heavier rock or thrash metal genres, including Metallica, Slayer, Black Sabbath, Red Hot Chili Peppers, Bush, Audioslave, Marilyn Manson, Slipknot, and System of a Down, but has also worked on albums by U2, Johnny Cash, Neil Diamond and others.
