Bohužel, i sám gielen přiznává, že to nedělal, jen rozhodoval. část rozhovoru k albu Revelations:
What was it like going solo production-wise, do you still work with others in the studio?
JG: In the end I believe that any track benefits from the contributions of different talented people. For this album I have worked with various people on my production team but in the end I was the person to judge the tracks and decide which parts would eventually be used. That part of producing is often the most difficult as you have so many options to choose from. In the end you have to follow your own heart, but some choices were very hard.
