Evanescence frontwoman Amy Lee is beyond stoked to finally share her new collection of hard rock songs with the world on Oct. 11. But the set didn't come easy. Musically, Lee says singing on the release was tougher than on previous Evanescence albums, and it pushed her guttural, goth-textured vocals as far as possible.

“[It’s] band members first, pianos and stuff next and then vocals for a really long time… It was, like, a month of just singing,” Lee told NME. “The songs are hard! I really pushed myself vocally.”

Lee went on to explain that producer Nick Raskulinecz (Foo Fighters) helped give her assurance in the final product: “Nick is an awesome producer. He really helped me get the plan and have confidence in the decisions that we made. For me, I have a lot of ideas and sometimes it just comes down to ‘ok, everything that I’m doing I have two options!’

“He’s awesome, because as I’m doing these things I’m asking him from the vocal booth or the piano room or whatever, ‘which one of these should I do?’ He’s good at helping me make a quick decision. I really trust his opinion because he makes great records.”

Evanescence recently released a new song off the forthcoming, self-titled album, called “The Other Side.”
