70s Rock: The Sound That Defined a Decade

70s rock opened with an ending and closed with an explosion.

The decade began in 1970 with the breakup of the Beatles.

Rock's psychedelic scene declined as the world lost icons like Jimi Hendrix and Janis Joplin.

Between those two moments, rock ran through a full sequence of distinct sounds.

• Hard rock
• Progressive rock
• Soft rock
• Glam rock
• Southern rock
• Arena rock
• Punk rock

Each one dominated the airwaves for a stretch before giving way to the next.

This is the story of how 70s rock rose, split into those movements, and broke apart by the decade's end.

The sounds and turning points of 70s rock, decade by decade.

How 70s Rock Began: The End of an Era

The breakup of the Beatles defined the start of the decade.

It also launched three major solo careers.

• John Lennon released Imagine.
• Paul McCartney released McCartney.
• George Harrison released All Things Must Pass.

A cultural shift arrived alongside those records, too.

By around 1972, a slogan was circulating that captured the mood.

"The '60s are over."

It signaled the end of hippie idealism and the rise of a more elitist, album-focused FM radio format.

That shift in radio habits was backed by a real change in how people bought music.

LP sales had overtaken singles sales for the first time in 1969.

That set the stage for the 1970s to be defined by full albums rather than three-minute radio hits.

The Rise of the Album Era

Musicians started treating the recording studio itself as an instrument.

This "Album Era" gave rise to complex, poetic progressive rock and virtuosic hard rock.

Hard rock in particular was built on guitar-driven energy and heavy riffs.

Three bands led that charge.

• Led Zeppelin
• Black Sabbath
• Deep Purple

Black Sabbath in particular is credited with inventing the darker lyrical themes that would come to define heavy metal.

Progressive Rock's Commercial Peak

Prog rock aimed for artistic credibility by folding classical, jazz, and world music into rock's structure.

Long solos and full concept albums were the result.

Pink Floyd and Yes were the genre's primary standard-bearers, pushing its technical boundaries the furthest.

The commercial numbers behind prog rock in the early 1970s are hard to overstate.

Together, five bands drove that commercial peak.

• Jethro Tull
• ELP
• The Moody Blues
• Yes
• Pink Floyd

Combined, they scored five number-one albums and sixteen top-ten albums on the US charts.

Pink Floyd's The Dark Side of the Moon stayed on the Billboard 200 for fifteen years, from 1973 to 1988.

Mike Oldfield's 1973 instrumental Tubular Bells sold 16 million copies after an excerpt was used as the theme for The Exorcist.

Not everyone inside the genre embraced the label, though.

Jethro Tull frontman Ian Anderson drew a line between two terms.

He preferred "progressive rock," a label he had used since 1969.

He felt "Prog Rock" carried connotations of grandeur and pomposity.

Pink Floyd's David Gilmour distanced himself from the whole category even more directly.

"I don't want to belong to any club that would have me for a member."

Soft Rock Takes Over the Mid-70s

While prog and hard rock chased scale, soft rock chased melody.

Derived from folk rock, the genre leaned on harmonies and acoustic instruments.

Carole King's 1971 album Tapestry became a landmark for the singer-songwriter movement and one of the decade's top sellers.

Three acts carried that soft rock sound through the mid-70s, when it peaked commercially and dominated radio airwaves.

• Bread
• James Taylor
• Fleetwood Mac

Fleetwood Mac's 1977 album Rumours became the best-selling album of the entire decade.

Glam Rock and Crossover Sounds

Glam rock was primarily a British phenomenon.

It was built on outrageous costumes, gender-bending performances, and campy science fiction references.

David Bowie was its most restless pioneer.

He later pushed into "blue-eyed soul" territory with two albums.

Young Americans arrived in 1975, and Station to Station followed in 1976.

The former was powered by the number-one hit "Fame."

John Lydon, the British punk musician known as Johnny Rotten, was once asked whether punk grew out of New York acts like Patti Smith.

He pushed back hard.

He argued that British glam artists had a far bigger influence on the scene.

• David Bowie
• T. Rex
• Slade

Southern Rock and the Outlaw Country Crossover

Southern rock fused rock, country, and blues around electric guitars and vocals.

The Allman Brothers Band and Lynyrd Skynyrd led that sound through the decade.

Country music found its own rock-adjacent moment in 1976 with the album Wanted! The Outlaws.

The record featured Waylon Jennings and Willie Nelson.

It helped define the "outlaw country" movement for a rock audience already primed for it.

Arena Rock's Commercial Peak

Arena rock combined hard rock's energy with progressive rock's complexity and theatrical staging.

Boston, Journey, and Styx built massive followings on that formula.

The Eagles became one of the most commercially successful acts in music history with 1976's Hotel California.

The album bridged country rock and mainstream rock in the process.

The Punk Explosion That Shook the Decade

Punk rock arrived as a direct, aggressive reaction against progressive rock's perceived pomposity and arena rock's corporate scale.

Punk magazine founding editor John Holmstrom put it plainly.

"Punk rock had to come along because the rock scene had become so tame."

The Ramones and Patti Smith were the earliest American acts to codify punk's stripped-down sound and DIY ethic.

In the UK, the Sex Pistols caused a sensation in 1977.

It represented the first serious challenge to established rock titans like the Rolling Stones.

The Damned actually beat them to the historical first, though.

The Damned released "New Rose" in October 1976, the first punk single released in the United Kingdom.

One single show did more to shape British music than almost any other event of the decade.

On June 4, 1976, the Sex Pistols played a gig in Manchester to a tiny audience.

That audience went on to form Joy Division, The Smiths, and The Fall.

The gig is also credited with inspiring the independent labels Factory Records and Creation Records.

Punk's DIY spirit got its own manifesto in December 1976.

The fanzine Sideburns published a now-famous illustration that became punk's rallying cry.

"This is a chord, this is another, this is a third. Now form a band."

The Great Schism That Ended the Decade

By 1979, rock had splintered in several directions at once.

Punk itself split into two paths.

• Accessible new wave
• Underground hardcore

Mainstream rock, meanwhile, began absorbing influences from disco and funk.

King Crimson's Robert Fripp broke up the band in September 1974.

He later said the genre had gone "tragically off course" and that English prog bands should have ceased to exist by that point.

For British punks, 1976 itself was remembered as a cultural "Year Zero."

It represented a total rejection of the musical establishment, including icons like Elvis and the Beatles.

Rock also crossed into new territory abroad during these final years.

Australian band AC/DC made their international debut in 1976 with High Voltage.

They reached global stardom by 1979 with Highway to Hell, which peaked at number 13 on the Kent Music Report.

Rock's reach even extended to film.

The 1975 movie Tommy starred The Who's Roger Daltrey in the title role.

The supporting cast included a few unexpected names from music itself.

• Elton John
• Tina Turner
• Eric Clapton

It was a clear sign of how far rock's cultural footprint had spread by the decade's end.
