The follow-up to 2005′s Rapture Of The Deep is released on April 29, and the singer is delighted with the results of having worked with producer Bob Ezrin.

He tells Noisecreep: "The one weakness that Purple always had, to me, was the sound of the records. Generally, I've always been slightly disappointed in the sound.

"This new album wipes away everything we've ever done ever. I'm thrilled with what Bob was able to do. The first monitor mixes I heard from these sessions, I just sat back and said, 'Oh my God, what he has done? It's perfect.' Everything was so clearly defined from the guitars to the Hammond organ. The definition is just remarkable.
