He’s the Prince of Darkness. The guy who bit the head off a bat. The reality TV patriarch who seemed permanently confused by his own toaster. But before the tabloids and the Ozzfest tours, there was a specific, gritty reality to the question of who did Ozzy Osbourne sing for that most casual fans actually get a bit wrong. They think it’s just Black Sabbath and then a solo career.
It’s way messier than that.
Ozzy didn't just walk onto a stage in Birmingham and become a god. He cycled through local bands with names that sound like they were pulled from a hat in a pub. He got fired. He quit. He joined a band that sounded like a flower-power nightmare before they realized they were meant to be heavy. To understand his voice, you have to look at the grime of the English Midlands in the late sixties.
The Early Days: Before the Sabbath Bloody Sabbath
Long before the world knew him as Ozzy, John Michael Osbourne was just a kid from Aston who desperately wanted to be a Beatle. He wasn't a "metal" singer because metal didn't exist yet. His first real foray into the music scene was a group called The Approach.
They weren't great.
They played soul and R&B covers. Imagine Ozzy trying to channel Otis Redding or Sam & Dave in a damp basement. It didn't last. After some friction, he moved on to a band called Music Machine, and then another short-lived outfit called The Rare Breed. This is where things get interesting because The Rare Breed featured a young bassist named Geezer Butler.
Even then, the chemistry wasn't quite there. The band folded after just a couple of gigs. Ozzy was so desperate for work that he reportedly put an ad in a local music shop window that simply read: "Ozzy Zig Needs Gig. Has own P.A."
Tony Iommi and Bill Ward, who had been playing in a band called Mythology, saw the ad. Tony actually remembered Ozzy from school—and not in a good way. He thought Ozzy was a "nutcase." But they needed a singer, and Ozzy had that P.A. system.
The Polka Tulk Blues Band and Earth
When you ask who did Ozzy Osbourne sing for, the answer eventually lands on Black Sabbath, but they didn't start with that name. The initial lineup—Ozzy, Tony, Geezer, and Bill—first called themselves the Polka Tulk Blues Band. It was a six-piece at first, including a slide guitarist and a saxophone player.

Can you imagine Black Sabbath with a sax? It would’ve been a disaster.
They trimmed down to a four-piece and renamed themselves Earth. This version of the band played heavy blues, inspired by the likes of Cream and Jimi Hendrix. They toured Europe in a beat-up van, playing long, improvisational sets. But there was a problem: there was another band called Earth that was actually getting radio play.
The legend goes that they saw a cinema across the street showing a Mario Bava horror film called Black Sabbath. People were lining up and paying money to be scared. Geezer Butler supposedly remarked that it was strange people would pay to be frightened, so why not make music that did the same thing?
The Black Sabbath Era: 1968–1977
This is the meat of the story. From 1968 to 1977, Ozzy sang for Black Sabbath, the band that effectively invented heavy metal. This wasn't just music; it was a cultural shift. While the rest of the world was singing about "peace and love," these four guys from a factory town were singing about "Hand of Doom," "Iron Man," and "War Pigs."
Ozzy's voice was the perfect instrument for Iommi’s downtuned, crushing riffs. He didn't have the operatic range of a Robert Plant or the grit of a Janis Joplin. He had something else: a haunting, nasal, siren-like quality that cut through the thick wall of sound.
The run of albums they produced is legendary:
- Black Sabbath (1970)
- Paranoid (1970)
- Master of Reality (1971)
- Vol. 4 (1972)
- Sabbath Bloody Sabbath (1973)
- Sabotage (1975)
By the mid-seventies, however, the wheels were coming off. Drugs, booze, and internal ego battles were shredding the band's cohesion. Ozzy was increasingly alienated from the musical direction Iommi wanted to take, which involved more keyboards and complex arrangements.
The Brief Departure and "Dirty Women"
Most people forget that Ozzy actually left Black Sabbath in 1977. For a very brief window, he wasn't singing for anyone. He was replaced by a singer named Dave Walker (formerly of Fleetwood Mac and Savoy Brown). Walker even appeared with the band on a BBC program called Look! Hear! performing an early version of a song that would become "Junior's Eyes."

But Ozzy came back. He didn't want to sing the songs Walker had worked on, so the band had to rewrite everything for the album Never Say Die!. It was a miserable experience for everyone involved. The tension was palpable. By 1979, Ozzy was officially fired for his escalating substance abuse and perceived lack of commitment.
The Blizzard of Ozz: Solo, but Not Alone
After being fired, Ozzy spent months in a hotel room, drinking himself into a stupor. He thought his career was over. He wasn't singing for anyone. Then Sharon Arden (later Sharon Osbourne) stepped in. She convinced him to start a new band.
This is a technicality that bugs music historians: Was he a solo artist, or was he in a band?
Initially, the project was intended to be a group called The Blizzard of Ozz. The first album was released under that name in some territories, but the label eventually marketed it as an Ozzy Osbourne solo album. He was singing for himself, but he was backed by a powerhouse lineup: Randy Rhoads on guitar, Bob Daisley on bass, and Lee Kerslake on drums.
Randy Rhoads changed everything. He brought a neoclassical sophistication to Ozzy’s sound that made the old Black Sabbath stuff look like caveman music. If you want to know who Ozzy sang for in his prime, it was this specific, lightning-in-a-bottle lineup.
The Weird Guest Spots and One-Offs
Over the decades, the list of who did Ozzy Osbourne sing for expanded into some truly bizarre territory. He didn't just stay in the metal lane. He was a frequent collaborator, often popping up in places you’d least expect him.
Take the 1980s duet with Lita Ford, "Close My Eyes Forever." It became one of his biggest hits. Or his work with Was (Not Was) on the track "Shake Your Head." In the early 90s, he even sang with Therapy? on a cover of "Iron Man."
He also did a legendary stint with The Alice Cooper Band for a guest appearance and famously performed with Post Malone on "Take What You Want" in 2019. It’s wild to think that a guy who started in a blues band in 1967 was topping the charts with a rapper over fifty years later.

The Reunions: Coming Home
The "who" eventually became the "original" again. Starting in the late 90s, Ozzy periodically returned to Black Sabbath. There were the Ozzfest reunions, the live albums, and finally, the studio album 13 in 2013.
While Bill Ward wasn't part of that final studio effort, Ozzy was once again singing for the entity that defined him. It brought his career full circle. He proved that even after decades of solo success—and despite the "Prince of Darkness" branding—his voice was most at home over Tony Iommi’s riffs.
The Nuance of the "Solo" Career
It’s easy to say "Ozzy Osbourne sang for himself" after 1979, but that’s a bit of a disservice to the legendary guitarists who shaped his sound. Each era of his solo career felt like a different band because the guitarists were so dominant.
- The Randy Rhoads Era: Neoclassical, bright, and technical.
- The Jake E. Lee Era: Polished, 80s hair-metal adjacent, but with a sharp edge (think "Bark at the Moon").
- The Zakk Wylde Era: Heavy, Southern-fried, pinch-harmonic-heavy metal.
When you listen to No More Tears, you aren't just hearing a solo singer. You're hearing a collaboration between Ozzy and Zakk Wylde. That partnership lasted on and off for decades, making it one of the most enduring "non-bands" in rock history.
Addressing the Misconceptions
One thing people often get wrong is the idea that Ozzy was the "leader" of Black Sabbath. He wasn't. Tony Iommi was the undisputed boss. Ozzy was the frontman, the mouthpiece, and the visual focal point, but he didn't write the riffs and he rarely wrote the lyrics. Geezer Butler wrote the vast majority of those iconic lines about Satan, war, and social collapse.
In his solo career, Ozzy took more of a directorial role, but he still relied heavily on his collaborators (like Bob Daisley and Lemmy Kilmister) to pen the lyrics.
Practical Takeaways for the Fan
If you're looking to explore the full vocal history of Ozzy Osbourne, don't just stick to the "Greatest Hits." To truly understand who he sang for and how his voice evolved, you need to dig into the fringes.
- Listen to "The Rebel": This is an unreleased track from the pre-Sabbath days (around 1969). It sounds more like a psychedelic pop song than metal. It shows a version of Ozzy that almost was.
- Track down the Dave Walker BBC session: It’s a glimpse into the brief moment when Ozzy wasn't in Sabbath and the band tried to move on without him.
- Check out "I Ain't No Nice Guy": His duet with Lemmy Kilmister from Motörhead's March ör Die album. It’s one of his most vulnerable vocal performances.
- Don't skip "Patient Number 9": His later work, featuring Jeff Beck and Tony Iommi, shows that even with a trembling voice, he still knows how to command a track.
Ozzy’s career is a lesson in resilience. He sang for blues bands, failed projects, the inventors of metal, and eventually, a solo machine that outlasted almost all his peers. He’s been fired, he’s quit, and he’s been resurrected more times than a horror movie villain.
To answer the question simply: Ozzy sang for the disenfranchised kids of Birmingham, the heavy metal faithful, and ultimately, for a legacy that redefined what a rock star could look like. Whether he was fronting Earth or standing on a stage at the Grammys with Post Malone, that weird, haunting voice remained unmistakably his own.
Moving Forward With Ozzy’s Catalog
If you're building a playlist to capture the full scope of who Ozzy Osbourne sang for, organize it chronologically rather than by popularity. Start with the 1970 self-titled Black Sabbath track to hear the birth of the "doom" vocal style. Then, jump to "Diary of a Madman" to hear the peak of his theatrical, multi-tracked solo harmonies. Finally, listen to "Degradation Trip" (a Jerry Cantrell song he almost sang on) or his actual guest spot on Black Label Society's "Stillborn." This progression reveals a singer who wasn't just a "character" on TV, but a versatile—if unconventional—vocalist who shaped three generations of music.
