And Rossdale says they brought in Nick Raskulinecz to produce the album as they didn't want any "softness" on the album. He tells radio show Elliot In The Morning:

"I wanted Nick to produce it because he does a lot of metal stuff. I didn't want to get any softness anywhere, so it is heavier. We had so much fun doing all the live shows that we really wanted to be able to have songs that go into the set and really make it happen.

He continues: "I began with more weird, dark noises and effects - garage electronic is what I keep calling it. It's not a disco record, but it's got weird sounds on it and good loops. It's cool, it's a good mixture."
