He said: “I’ve always tried to approach how I do what I do the same way I feel that the great vocalists of all time would have approached it – whether it’s Judas Priest’s Rob Halford or Ronnie James Dio.
“I try to be as pure and as direct and as resonant as I possibly can within my own respective abilities – not that I’m anywhere close to either one of those two. They're human freaks of nature. May one of them rest in peace and may the other stay with us for many, many years to come.
“Between the two of them in particular, you’re talking about two of the greatest voices of all time. Certainly not to not include what, in my opinion, was not only one of the greatest vocalists to ever sing, but the greatest frontman that the world has ever seen in Freddie Mercury.
“His range, his charisma, his presence, everything about him, just the quintessential frontman.”
Disturbed are currently on tour, with their next two shows scheduled to take place in Russia.
They’ll return to the US and Canada later in the summer for further dates which will stretch through until October 11 in support of their latest studio album Evolution, which was released last year.
