During an interview with Stevie Rennie on October 28, 2014, Shadows mentioned that he on purpose had changed his voice to become less raspy and distorted while touring in 2014. The change was due to longer live shows lasting from one and a half to two hours in support of "Hail to the King". Shadows went on to say that "you better be taking care of yourself or you're gonna be cancelling shows" and "I wanted to hit notes over the rasps".
