👍Ronnie James Dio / ❤️Rob Halford / 😍Bruce Dickinson 👍 Ronnie James Dio Ronnie James Dio was metal’s majestic voice and mythmaker. From Rainbow to Black Sabbath to his solo career, Dio’s operatic delivery and fantasy-driven lyrics made songs like “Holy Diver” and “Heaven and Hell” iconic. He brought dragons, swords, and cosmic struggles into heavy metal’s vocabulary—without ever sounding silly. His powerful range, impeccable control, and commanding stage presence elevated him above his peers. Beyond his voice, Dio’s lyrics inspired generations to fight inner demons and believe in self-worth. A pioneer of power and purity in metal, his influence remains deeply woven into the genre’s fabric. ❤️ Rob Halford Rob Halford is metal’s thunderous scream and leather-clad avatar. As Judas Priest’s frontman, he redefined what a heavy metal vocalist could be—with sky-piercing highs on “Painkiller” and “Victim of Changes.” Halford also gave metal its visual identity, blending biker bravado with theatrical command. His stage presence is towering, his voice unmatched in stamina and power. Offstage, Halford’s bravery as one of the first openly gay metal icons gave strength to fans worldwide. His technique, intensity, and defiant grace make him not just a vocalist—but a metal deity. 😍 Bruce Dickinson Bruce Dickinson turned heavy metal into airborne opera. With Iron Maiden, his soaring vocals and literary lyrics crafted epic narratives like “The Trooper” and “Hallowed Be Thy Name.” A trained pilot, fencer, and author, Dickinson brings intellect and theatricality to the genre. His voice—agile, piercing, heroic—is Maiden’s battle cry, delivering grandeur and power in equal measure. Whether sprinting across stages or belting with spine-tingling clarity, Bruce is the consummate performer. Few can match his blend of energy, storytelling, and technical mastery. Comparison Dio enchanted, Halford thundered, and Dickinson

In an exclusive extract from his recently released book Biblical, Rob Halford reflects upon trying to create The Three Tremors with Ronnie James Dio and Bruce Dickinson, and he also reveals who would be in his dream rock and metal supergroup

.Biblical is Rob Halford’s second book, following his hugely successful autobiography Confess. In this new book Rob shares reflections on music, touring, bands and more after fifty years of living the metal life with Judas Priest.

The closest I’ve ever come to being in a supergroup was the Three Tremors concept back in 2000. It was my partner Thomas’s idea. We were talking about opera’s Three Tenors—Pavarotti, Plácido Domingo, and José Carreras—and a light bulb came on over Thomas’s head: “Hey! Wouldn’t it be great to have three metal singers called theThree Tremors?”

We tried to make it happen, firstly with me, Bruce Dickinson, and Ronnie James Dio (how cool would that have been?!) and then me, Bruce, and Geoff Tate from Queensrÿche. Everyone was dead up for it, but sadly we wouldn’t make our schedules match up and make it work.

As it happens, there is a Three Tremors trio of metal singers now, with my temporary Priest replacement, Tim “Ripper” Owens, in it. When I first heard, I was pissed off they had nicked our name without asking us—but we never trademarked it. Well, it is what it is. Supergroups work if they are just a bunch of musicians getting together to play for the love of the music, with no egos attached. An example is Bad Penny, a group made up of guitarist Mike Holzman, former Queen + Paul Rodgers bassist Danny Miranda, and Blue Öyster Cult drummer Jules Radino
