In the late spring of 1973, Black Sabbath was at a crossroads. Their live album had been shelved. Management wanted new material. And the band, still chasing the drug-soaked haze that had fueled Vol. 4, made what seemed like a logical decision: go back to Los Angeles. Same Bel Air mansion. Same studio. Same California high-grade toot. 

Their destination was the Record Plant. During the 1970s, this was the premier recording studio for the industry’s biggest names, hosting everyone from Frank Zappa to Jimi Hendrix. But when Sabbath arrived, they found they weren’t the only musical heavyweights in the building. One of the biggest names on the planet was occupying the studio next door: Stevie Wonder. Wonder was in the middle of recording his landmark album Innervisions.

Wonder was untouchable in 1973. Innervisions would be his third album in a flawless five-album run. This was Stevie Wonder at his absolute peak—and so the Record Plant belonged to him.

The creative safe space Sabbath remembered from a year prior was gone. The studio was dominated by a massive, room-filling monstrosity of cables and modules known as TONTO.

The Original New Timbral Orchestra was a massive synthesizer setup that looked more like a spaceship cockpit than an instrument. It took up so much space that Sabbath couldn’t get all their gear in the studio. When Wonder was asked to look at how much space his rig was taking up. Wonder replied. “I don’t see it”.

But Little Stevie’s keyboards wasn’t their biggest problem. Their biggest enemy was the silence in their own heads.

For the first time in his Sabbath career, Iommi hit a creative wall. As he later explained:

“I couldn’t come up with anything. It was just too much pressure for me, to have to be the only one that was coming up with ideas. Nobody else wants to do it; I had a mental block and I just couldn’t get around.” [Popoff, Martin. Sabotage! Black Sabbath in the Seventies (p. 184).]

This was uncharted territory. Their song writing process had mostly followed the same blueprint: Iommi brings in a riff, the band locks in, the track takes shape. His bandmates had ideas—but they stayed buried, held back by hesitation and self-doubt. This would begin to change with Sabbath Bloody Sabbath. But there, under the California sun, the creative well had run dry.

Ozzy said, “Tony was grumbling about doing all the work in the studio, which meant he had no personal life. He had a point. But then again, Tony loved being in the studio – As technology improved during the seventies, the temptation was always to add one more track, then another, then another… Tony couldn’t get enough of all that stuff. And no one ever argued with him, because he was the band’s unofficial leader.” [I am Ozzy]

After a few weeks of frustration, the band decided to abandon Los Angeles and try again back home in England. According to author Mick Wall, before leaving LA, Tony walked into a hairdresser’s on Hollywood Boulevard and told them to cut his hair short. When he returned to the Bel Air mansion, he’d shaved off his moustache as well — a small act of reinvention, a physical reset meant to shake something loose.

The moustache had been part of Tony’s look for years. He originally grew it as a way to hide a childhood scar.

When he was a kid, an older boy once chased him with a large spider. Tony ran down a gravel road, tripped, and slammed face-first into the ground, ripping up his lip. The scar stayed, and the local kids wasted no time giving him a nickname: “Scarface.”

The teasing bothered him so much that when puberty finally hit, he grew a moustache to cover it. He would keep his mighty stache for years — until that day in Los Angeles.

The band returned to the UK — but the riff blockage didn’t let up.

Iommi said: We got back home to England all depressed. The other three thought, that’s the end of that now. I remember Geezer and Ozzy talking like it was all over. I panicked. I thought, blimey, it’s never going to happen again. My God, I’ve lost it all!” [Excerpt From Iron Man]

Geezer said: “If Tony’s not coming up with anything, and they’re not accepting any of my offerings, it’s pointless carrying on. Maybe we’ve gone as far as we can go. Maybe this is how it all ends.” [Geezer Butler – Into the Void-HarperCollinsPublishers] 

As many times before, the Sab 4 just kept pushing forward. That next push was finding a place to rehearse and write.

They chose Clearwell Castle, a mock-Gothic mansion in Clearwell, Gloucestershire, on the edge of the Forest of Dean. Secluded and removed from the noise, they had the space to regroup and write their next album without distraction.

Clearwell Castle had been privately owned by Frank Yeates. Built in the early 18th century, the castle was already some 250 years old when it came into his hands. His father had worked there as a gardener, and Frank himself had been born within its walls. In 1953 the former baker purchased the property for £3,000. 

What he moved his family into was barely a home — no electricity, no real habitation, just stone walls and the wreckage left by a catastrophic 1929 fire. The Yeates family lived in caravans on the grounds while the rebuild crawled forward.

To fund the work, Yeates opened the castle to the public: weddings, medieval banquets, art shows, and other various community events. Word eventually reached the music world, and in 1971, Badfinger became the first notable band to stay there, remaining for six months and even being offered the chance to buy the place for £30,000. They considered it, then passed.

Black Sabbath arrived in May 1973. Just months later, Deep Purple would use the same walls to unveil their Mark III lineup — introducing David Coverdale and Glenn Hughes — while rehearsing material for Burn. Throughout the decade, Clearwell became a quiet refuge for rock royalty: Bad Company, The Sweet, Led Zeppelin, and others. Ozzy himself would return in 1980 to rehearse with his Blizzard of Ozz bandmates.

It should be noted that the castle’s current website — now primarily a wedding venue — claims that Led Zeppelin, Badfinger, Deep Purple, Queen, and Whitesnake recorded albums there. That’s not accurate. There was never a recording studio at Clearwell. When artists did record there, they brought in mobile units parked outside. Of the bands mentioned on their website, only Whitesnake actually recorded an album there. Queen as a band never stayed there.

Sabbath didn’t go to Clearwell to record an album; they went there because they needed a place to write and rehearse. It was during these early rehearsals that Clearwell Castle began to reveal another side of itself.

While playing in the dungeon—a large, multi-room space made up of an armory, adjoining chambers, and a lounge—the band noticed a dark, cloaked figure walk past the doorway. Assuming someone had wandered into the castle, Tony Iommi and one of the roadies immediately gave chase. They followed the figure down a corridor and watched it enter a room at the far end. When they rushed inside, the room was empty. There were no other exits, no places to hide—no logical explanation for where the figure had gone.

When the castle’s owner, Alice Yeates, was asked about the incident, her response was delivered casually: it was simply the castle’s ghost, a figure said to appear from time to time. After that night, Geezer Butler chose not to sleep in the castle at all, driving home every evening instead.

As the tension lingered, fear gave way to something more familiar. Playing pranks on one another was already part of the band’s dynamic, long before Clearwell Castle and long after it. The setting simply gave their usual mischief a darker backdrop, with the castle’s reputation amplifying behavior that was already second nature to them. With so much trickery in play, it often became difficult to tell where a genuine disturbance ended, and another band member’s joke began, further blurring the line between imagination and reality inside the castle.

Another room carried a darker legend. The castle’s owner warned Bill Ward that he might experience something unusual while staying there. She told him about a maid who had once lived in the room, become pregnant by the castle’s owner, and ultimately jumped from the window with her baby, taking both their lives. According to local lore, her ghost was sometimes seen running through the room before leaping again.

Disturbed by the story, Ward slept with a large dagger beside his bed. When Iommi asked what he planned to do with it, Ward began to answer—only for Iommi to cut him off: “Bill, it’s a ghost. How are you going to stab a ghost, for Christ’s sake?” 

In reality, the band had nothing to fear from the castle, but the castle had something to fear from them.

One night, Ozzy fell asleep in front of the castle’s large fireplace after stoking it too high.

Ozzy said, “All I can remember is waking up at three o’clock in the morning with a funny feeling at the end of my leg, then jumping up, screaming, and hopping around the room with this flaming boot, looking for something wet to put it in. Everyone else thought it was hilarious. Geezer just looked at me and said, ‘Got a light, Ozzy?’ But the smile was soon wiped off his face when an ember flew off my boot and set the carpet on fire.”

Ozzy ran and got a jug of Bill Ward’s cider to put out the blaze. 

In a castle that had already come close to being lost once to fire, the greatest threat wasn’t something lingering in its walls; it was from having Black Sabbath stay there. 

Sadly, Frank Yeates died in the castle he owned just a couple of weeks after Black Sabbath had left in late July 1973. Unfortunately, I couldn’t find the cause of his death.
