The Band

If there's one band that shaped an entire musical genre and influenced entire generations, it's Black Sabbath. Born in Birmingham, England, in the late 1960s, the group comprised of Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward didn't just play heavy rock—they created heavy metal as we know it.

The band's last studio album was titled '13,' and their debut album was released on Friday the 13th. So, let's list 13 reasons why Black Sabbath is, without exaggeration, the most important band in rock history.

They invented heavy metal

Before Sabbath, bands like Led Zeppelin, Hendrix, and Cream were already exploring heavy sounds and hard rock. But Black Sabbath was the first group to combine heaviness and lyrics with dark themes about darkness and terror, with sonic intensity at the center of their approach. The band's name itself was taken from a 1963 horror film – Black Sabbath.

The release of the album Black Sabbath in 1970 is considered by many to be the turning point of metal.

The founding members are still alive

In a world where so many bands lose members too soon, the four original members of Sabbath are still alive. This in itself is a rare feat.

The original lineup may yet reunite one last time:

Ozzy Osbourne - vocals

Tony Iommi - guitar

Geezer Butler - bass

Bill Ward - drums

Black Sabbath's final show, with the original lineup, will take place on July 5th as part of the "Back to the Beginning" festival in Birmingham, England, the band's hometown. This show marks the band's final farewell to the stage, and also Ozzy Osbourne's final solo performance.

A Unique Blend of Musical Influences

Sabbath's sound is the result of a fusion of blues, jazz, psychedelic rock, and classical music. The band created a sound unlike previous hard rock; a dark, drawn-out, and powerful sound was something new and frightening—and this won over a legion of fans, who later dubbed it Heavy Metal.

Tony Iommi reinvented the way to play guitar

After losing part of both of his fingers in a workplace accident, Iommi had to adapt his playing style. This limitation gave rise to his unique style of heavy, dragging riffs that utilized a tritone (known as diabolus in music) and became a hallmark of metal.

Geezer Butler Created the Lyrical Soul of Metal

With lyrics inspired by the occult, religion, and the apocalypse, Geezer Butler, who was raised in Christianity from childhood, gave Sabbath a lyrical depth previously unknown in rock. He paved the way for future bands like Metallica, Ghost, and Slayer.

And despite gaining this aura of an occult band, the members of Black Sabbath were always influenced by Christianity.

They Were Truly Scary

Sabbath's dark visuals, macabre themes, and dense sound instilled fear in parents—and that was part of their appeal. Their first album sounded like a horror movie soundtrack.

The Black Sabbath album was released on Friday, February 13, 1970, adding to its spooky atmosphere.

The sound coming from the speakers of their first album gave many young people chills and nightmares back in the day. And some kids loved it.

They Overcame Ozzy's Departure

When Ozzy Osbourne left the band in 1979, many thought it was the end. But Sabbath surprised everyone by releasing masterpieces like Heaven and Hell, with Ronnie James Dio on vocals, proving that the band was bigger than its members.

It was during this tour for the Heaven and Hell album that Dio made the famous "horns" gesture with his hand, later adopted as a sort of "sign of recognition" by metal fans.

It Didn't Just Talk About Horror Movies

Black Sabbath didn't just talk about demons, black magic, and horror movie themes. Songs like "War Pigs" and "Children of the Grave" denounced war, political manipulation, and the alienation of youth.

But themes like the end of the world, drug abuse, faith and religion, mortality, mental insanity, social control, and manipulation—all this diversity of themes can be found in the band's lyrics.

They influenced every metal subgenre

Doom, stoner, sludge, thrash, black, death metal… All these styles were born under Sabbath's shadow. Riffs like those in "Into the Void" or "Sweet Leaf" still serve as references for new bands today.

Covers of their songs can be seen paying homage to the band on albums by bands of various styles.

Several collections of covers in tribute to Black Sabbath can even be found. See the collections Nativity in Black volumes 1, 2, and 3.

Ozzy became a pop icon—without losing his title as the "Prince of Darkness"

Ozzy Osbourne, throughout his musical career, has become famous for several strange and intriguing stories.

This has led to him becoming a global figure, both as a rocker and as a reality TV star.

From 2002 to 2005, the MTV reality show "The Osbournes" elevated Ozzy Osbourne to a pop idol even outside the circles of rock and heavy metal fans. But even with this fame outside the music world, he has never ceased to be a living metal legend. His influence is undeniable.

They've Remained Relevant for Decades

Unlike other bands from the '70s, Sabbath never became dated. They had several classic vocalists, such as Ozzy Osbourne, Ronnie James Dio, Ian Gillan, and Tony Martin, and they underwent several musical changes throughout their career, yet they never lost their relevance in the music industry. They've stood the test of time, winning fans across the grunge, nu metal, and even digital era generations. Their riffs still go viral on social media.

They said goodbye in style

Their last full-length studio album, 13 (2013), debuted at number one on the UK and US charts—a feat not even their 70s classics had achieved. It was the well-deserved crowning achievement of an epic career. A tour was also held to support the album.

Following this release in 2016, an EP was released featuring the last four unreleased tracks from the recordings of 13 and four more songs recorded live on that tour, titled "The End."

On February 4, 2017, the band called it quits in the city where it all began, Birmingham.

The Last Show - Ozzy Osbourne's Farewell to the Stage

In February 2025, the original lineup was announced to reunite for a charity concert in Birmingham on July 5, 2025, for Ozzy Osbourne's farewell show.

Without Sabbath, metal wouldn't exist.

Metallica, Slayer, Megadeth, Iron Maiden, Pantera, Slipknot, Alice in Chains, … all have Sabbath's DNA.

An entire subgenre of metal, "Doom Metal," is influenced by Black Sabbath's work.

Their unique style of heavy, dragging riffs using the tritone ("diabolus in musica") combined with the heavy drumming provided by Bill Ward has become a metal trademark.

They were the architects of heavy metal, and the world of rock has never been the same since.

The legendary Black Sabbath will conclude their journey on stage with a historic and unmissable show: "Back to the Beginning." The concert, scheduled for July 5th in Birmingham, the band's hometown, will be broadcast live worldwide.

Tickets for the live event, which promises to be the biggest heavy metal show of all time, Was on sale at www.backtothebeginning.com. If you're a fan of heavy rock, this is a farewell you can't miss!

Conclusion

Black Sabbath wasn't just an important band—it was the definitive band. They created a genre, an aesthetic, a sonic language. They influenced everything that came after, directly or indirectly.

If Rock N' Roll and Heavy Metal are what we know today, much of it is due to Black Sabbath's influence.

They are found in soundtracks for films, series, and video games.

If metal is one of the most powerful and respected genres in the world today, we owe it to Sabbath.
