Through interviews over the years, Hetfield has identified three singers he considers the greatest of all time. His choices reflect not only vocal ability, but also emotion, authenticity, influence, and longevity. From operatic metal power to raw grunge emotion and classic heavy metal precision, Hetfield’s list spans different styles while remaining deeply rooted in intensity and honesty.
James Hetfield Best Singers Pick #1: Ronnie James Dio
At the very top of the James Hetfield best singers list stands the late and legendary Ronnie James Dio. For Hetfield, Dio was not just great — he was unmatched.
Dio’s career spanned influential bands such as Rainbow, Black Sabbath, and Heaven & Hell, and his voice remained powerful well into his later years. What impressed Hetfield most was not only Dio’s range, but the strength and clarity he maintained across every note.
While working on the 2014 tribute album Ronnie James Dio – This Is Your Life, Metallica recorded the “Ronnie Rising Medley,” which paid homage to Dio’s early Rainbow era. It was during this project that Hetfield fully realized just how demanding Dio’s vocals truly were.
Hetfield once recalled asking Dio about his vocal warm-up routine, expecting some complex technique or strict discipline. Dio’s response was surprisingly simple: a small glass of wine before singing. According to Hetfield, Dio wasn’t exaggerating — he was simply a natural-born singer with effortless control and power.
Beyond mutual respect, the admiration went both ways. Dio openly praised Metallica and singled out “Enter Sandman” as a standout metal song, noting how the band successfully stepped into new musical territory at exactly the right moment.
Dio’s influence on metal vocals remains undeniable, and for Hetfield, no singer has ever surpassed him.
James Hetfield Best Singers Pick #2: Layne Staley
Second on the James Hetfield best singers list is Layne Staley, the haunting and emotionally raw voice behind Alice in Chains.
Hetfield has repeatedly described Alice in Chains as his favorite grunge band, praising their sound as timeless, dark, and deeply original. What set Staley apart, in Hetfield’s view, was his ability to channel pain, vulnerability, and power all at once — something few vocalists have ever done convincingly.
Although the two were not personally close, Hetfield frequently attended Alice in Chains shows in the early 1990s, even leaving studio sessions early just to see them perform live. To him, their music stood out from the Seattle scene because it didn’t chase trends — it created its own space.
After Staley’s tragic passing in 2002 at just 34 years old, Alice in Chains eventually returned with William DuVall on vocals. In 2006, Hetfield joined the band on stage in Germany and later in San Francisco to perform “Would?”, honoring Staley’s legacy in front of massive crowds.
Hetfield has continued to praise the band’s later work, especially the album Black Gives Way to Blue, highlighting how the group managed to move forward without erasing its past. For him, Staley’s voice remains irreplaceable — a reminder of how powerful honesty in music can be.
James Hetfield Best Singers Pick #3: Rob Halford
Rounding out the James Hetfield best singers list is the “Metal God” himself, Rob Halford.
As the frontman of Judas Priest, Halford helped define what heavy metal vocals could be — soaring highs, piercing screams, and razor-sharp control. Hetfield has consistently credited Judas Priest as one of Metallica’s biggest influences, calling them a blueprint for what a true metal band should be.
Hetfield and Halford have shared the stage multiple times, including unforgettable performances of “Rapid Fire” during Metallica shows. Their mutual respect extends beyond collaboration; even decades later, Hetfield has been spotted in the front row, watching Judas Priest like a fan rather than a fellow legend.
One of Hetfield’s favorite Judas Priest songs, “Victim of Changes,” showcases everything he admires about Halford: drama, precision, and emotional intensity. According to Halford himself, Metallica’s global success represents a level of achievement few bands in history ever reach — a sentiment that underscores the mutual admiration between the artists.
