Black Sabbath
Black Sabbath invented heavy metal and then spent decades demonstrating its management style. The 1979 firing of Ozzy Osbourne — dismissed, in the band's own telling, not for excess but for excess beyond even their tolerances — split metal's founding house into two dynasties: Sabbath's revolving-door singer decades, and the Osbourne empire run by Sharon Arden, whose subsequent wars with her own father (Sabbath's fearsome ex-manager Don Arden) and with the band form a second dossier inside this one.
Formed in Birmingham in 1968, Black Sabbath — Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward — invented heavy metal essentially by accident, tuning down to accommodate Iommi's factory-mangled fingertips and discovering that doom sells. Within a decade they were the genre's founding institution; within eleven years they had fired their singer.
The 1979 dismissal of Osbourne is the archive's most quoted firing because of its grounds: in a band whose consumption was industrial, Ozzy was let go for being unreliable even by those standards — delivered the news, in a detail all parties confirm, partly through his old friend Bill Ward, because no one else would do it. The firing created two empires: Sabbath continued with Ronnie James Dio (twice), Ian Gillan, Glenn Hughes, Tony Martin and others through two decades of splits, reunions and litigation; Ozzy, managed and married by Sharon Arden, became the biggest solo act in metal — after Sharon extracted him from her own father's management company, igniting a family war involving lawsuits and, per multiple accounts, released dogs.
The file closes warmly, which is rare here: the original four reunited in 1997, recorded a farewell No. 1 album (13, 2013), ended touring in 2017 in Birmingham, and — after Bill Ward's long, contract-driven estrangement — played one final hometown show with all four founders in July 2025, weeks before Osbourne's death. The thread, against every precedent in this archive, was re-tied at the end.
Timeline of unravelling
Earth becomes Black Sabbath
Four Birmingham men rename their blues band after a horror film and release Black Sabbath and Paranoid within seven months of each other in 1970. Metal now exists. So does the band's relationship with management contracts, which will supply this file for decades.
The Don Arden / Patrick Meehan years
The band signs with managers whose accounting practices they will spend years unwinding; by mid-decade, by their own memoirs, the men who invented metal are startlingly short of money and deep in litigation with their own representatives — the era that teaches Sharon Arden, watching from her father's office, everything.
Ozzy is fired
After years of escalating unreliability during the Never Say Die era, the band dismisses Osbourne — Bill Ward deputized to deliver the news to his friend. The stated grounds, immortal in this archive: his excesses had become unmanageable even for Black Sabbath.
Two dynasties diverge
Sharon Arden takes over Ozzy's career and marries him, prying him from her father Don's company — a rupture producing lawsuits and a family estrangement lasting nearly two decades. Sabbath hires Ronnie James Dio and rebounds with Heaven and Hell; Ozzy's Blizzard of Ozz outsells them. Everyone declares victory.
Dio quits amid the mixing-desk affair
The Dio lineup fractures over accusations — denied, and never substantiated — that Dio snuck into the studio to raise his vocals in the Live Evil mixes. Dio departs with drummer Vinny Appice to form Dio. The band replaces one legendary singer dispute with a rotation of them.
The revolving door
Ian Gillan (one album, recorded largely at a country manor whose bar did not survive), Glenn Hughes, Ray Gillen, Tony Martin (twice), Dio again (Dehumanizer, 1992, ending again in acrimony when Dio refuses to open for Ozzy) — Iommi keeps the name alive through a decade in which the lineup changes faster than the album cycle.
The Costa Mesa insult
When Ozzy's 'retirement' shows request Sabbath as openers, Dio refuses to play support to the man he replaced and quits mid-tour; Rob Halford of Judas Priest learns the set on days' notice. The original four then reunite for four songs at the finale — the first flicker of the ending.
The reunion and the Ward asterisk
The original lineup reunites for Ozzfest 1997 and the Reunion live album (their first US top-20 in years). The peace is real but papered: Bill Ward's participation becomes intermittent, foreshadowing the contract dispute to come.
13 — three-quarters original
The announced full reunion album proceeds without Ward, who publicly declines over a contract he calls unsignable; the band's statements dispute his framing in a painful public exchange. With Rage Against the Machine's Brad Wilk drumming, 13 becomes the band's first UK No. 1 album since 1970 and first US No. 1 ever.
The End, Birmingham
Sabbath concludes touring with two hometown shows — Ward still absent, the wound still open in interviews on both sides. It appears to be the final word.
Back to the Beginning — all four, one last time
The original four reunite for a single Birmingham charity mega-show, Ozzy performing seated, Ward restored behind the kit, metal's entire aristocracy in support. Osbourne dies seventeen days later. This archive, which specializes in threads that snap, records one deliberately re-tied at the very end.
Who held the thread
Black Sabbath's story ended in 2025 with a completeness this archive almost never gets to record: all four founders, one stage, one city, seventeen days before the end. The Back to the Beginning show raised a reported nine figures for charity and settled, by performance rather than press release, every remaining question about whether the original thread could hold.
The historical file remains instructive on two fronts: management (the Arden-era contracts became the cautionary syllabus for a generation of British bands) and succession (the Dio and Martin eras proved a founding institution can survive its icon, profitably, for decades — while never quite convincing anyone it should). Metal's founding house closed its books balanced, which in this archive counts as a miracle.
