Watch Johnny Cash’s 1969 concert at San Quentin

Johnny Cash is one of the most recognizable names in country music, but by the 1960s, he was also a rock icon. Part of that status was due to his outlaw identity and willingness to play for true outsiders. This documentary from one of his most famous performances shows why.

'All your life, you will be faced with a choice. You can choose love or hate … I choose love.'

-Johnny Cash (1932-2003)

Carole King wrote—and later regretted—the song 'He Hit Me (And It Felt Like a Kiss),' which she now believes excuses domestic violence.

'Take Me Out to the Ballgame,' the song that's now a 7th inning tradition at every MLB game, was inspired by a billboard advertisement.

The music theory behind a lonesome country classic

Townes Van Zandt's "I'll Be Here in the Morning" might read like a clever inversion of a standard country music trope. But Cush, a musician in his own right, walks through the song's structure to show how its story is far more complicated than its lyrics suggest.

Country musicians grappled with the outlaw archetype on screen

As country grew more popular, some of its biggest stars leapt to the silver screen, with Johnny Cash in "Five Minutes to Live," Kris Kristofferson in "Pat Garrett and Billy the Kid," and Dolly Parton in "9 to 5." Kristin Hunt notes that all of these films featured country stars toying with the outlaw archetype, a prevalent theme throughout the history of country music.

Judee Sill's admirers hear a legend gone before her prime

The singer-songwriter released only two albums in her lifetime: 1971's self-titled and 1973's "Heart Food." Critics and contemporaries (including Graham Nash and David Crosby) praised both, though they were commercial flops. She died of a drug overdose in 1979 and had grown so obscure by then that no obituary was published. In the early 2000s, her recordings were reissued and found a new generation of fans.

'Nebraska' was a sharp pivot inspired by proto-punk band Suicide

After "Born to Run," Springsteen's songwriting turned darker on subsequent albums "Darkness on the Edge of Town" and "The River," as he began exploring the harsher realities of adulthood and working-class life, but "Nebraska" was his most gothic, featuring haunted songs partially inspired by the abrasive proto-punk duo Suicide.

He made a name with a short story about jumping frogs

Twain’s first big break came with “Jim Smiley and His Jumping Frog,” a fictitious story that appeared in a 1865 edition of the New York Saturday Press. (When it was republished elsewhere, the title was changed to “The Celebrated Jumping Frog of Calaveras County.”) That year, American poet James Russell Lowe called it “the finest piece of humorous literature yet produced in America.”

Woody Guthrie wrote 'This Land Is Your Land' as a sarcastic response to 'God Bless America.'

The 1927 'Bristol Sessions' birthed the modern country industry

Country music has been around since the early American colonies, but the modern country industry began in 1927 in a small town on the Tennessee-Virginia border. Here, Ralph Peer recorded songs from the Carter Family, Jimmie Rodgers, and a dozen more artists through a 12-day stint called "The Bristol Sessions."

Bruce Springsteen's 'Nebraska' was influenced by writer Flannery O'Connor

Springsteen became obsessed with the "Southern gothic" writer when he began working on the songs for "Nebraska," inspired by O'Connor's tragic characters and grotesque imagery.

Why Neil Young is sometimes called 'the godfather of grunge'

The legendary singer-songwriter's work with his band Crazy Horse, especially "Rust Never Sleeps" and "Ragged Glory," married infectious melodies with overpowering guitars, a formula that many grunge acts would replicate. Young would go on to perform with Pearl Jam (like in the performance of "Rockin' in the Free World" below) and record the 1995 album "Mirror Ball" with them.

Dolly Parton released her first recording at age 13, a rockabilly number she cowrote called 'Puppy Love.'

Before becoming a country superstar, Dolly Parton recorded girl group-style singles as a teenager, including one that became a hit outside the US.

Prince wrote numerous hits for other artists

Prince is renowned as a performer, but he's also one of the great American songwriters, having penned career-defining songs for acts like Sinead O'Connor ("Nothing Compares 2 U"), the Bangles ("Manic Monday"), and many others.

Bob Dylan wrote and recorded songs that later became hits when they were covered by artists like Jimi Hendrix, Adele, and Guns N' Roses.

Daniel Johnston's home recordings have inspired countless rock legends

The singer-songwriter self-released cassettes in the early '80s that were not fit for the radio—their sound quality was poor, and the songs were often little more than an organ and Johnston's high-pitched voice, singing about things like Casper the Friendly Ghost. The tapes eventually found their way to alternative tastemakers, who lauded the songs' brilliance and inspired a cult following that has admired Johnston's music for decades.

Springsteen is considered one of rock's greatest songwriters

Prince wrote a song for Kenny Rogers under the name Joey Coco

The enigmatic artist was wildly prolific and, when he wasn't churning out his own records, often wrote and produced other people. He contributed "You're My Love" to country icon Kenny Rogers' 1986 album "They Don't Make Them Like They Used To," though you wouldn't have known that reading the record's credits because the song was attributed to Joey Coco, a pseudonym Prince sometimes used.

The song 'Hungry Heart' was written for punk icons the Ramones, but Bruce Springsteen's manager convinced the singer to record it himself.

Ray Charles' 'Modern Sounds in Country & Western Music' albums blurred genre lines

Released in the midst of the Civil Rights Movement, Charles’ records showed that country music, by then largely segregated, was an American music, no matter one’s background.

Watch Bruce Springsteen's 1985 performance of Woody Guthrie's 'This Land Is Your Land,' which he calls 'the greatest song ever written about America.'

Billie Holiday's label refused to release 'Strange Fruit,' a protest song about lynching, because of fears of negative reactions from southern retailers.

A research study found that Springsteen's popularity is due to his lyrics' authenticity

The Penn State study compiled lyrics from 18 albums and analyzed the words that "convey genuineness and honesty" and those that suggest cognitive activity. They found that Springsteen's songs are often focused on the present and "tend to express positive emotion," which they believe might explain why his fans are so devoted.

1982's ‘Nebraska’ was recorded alone at home, a rarity at the time for a major artist

“Born to Run” became a hit in part due to its massive sound, something that was only possible thanks to the magic of the studio. That continued with 1980’s “The River,” which gave Springsteen his first top 10 single. With “Nebraska,” though, Springsteen abandoned the studio, opting to release the spare recordings he made at home, by himself. At the time, such a decision was a rarity for a platinum artist.

Chuck Berry was one of the genre's early innovators

A pioneer of rock ‘n’ roll, Berry redefined music in the 1950s with hits like "Maybellene" and "Johnny B. Goode." Drawing from blues and country, his signature riffs and storytelling influenced generations of artists.

Paul Simon recorded his landmark album 'Graceland' in South Africa, in defiance of a UN-approved cultural boycott.

The poem behind 'Strange Fruit'

"Bitter Fruit" was written by Abel Meeropol, a teacher, under the pseudonym Lewis Allen, after seeing a photograph of a lynching. Eventually, he set the words to music, and the song was then performed by his wife and other singers. In 1938, he played it for Holiday, who began performing it at the New York's Cafe Society.

Outlaw Country was a subgenre that emerged in the 1970s

Outlaw country was a reaction against popular country music produced in Nashville. The name's origin is disputed, but it was firmly established with the 1976 album “Wanted! The Outlaws,” a record featuring songs by Waylon Jennings, Willie Nelson, Jessi Colter, and Tompall Glaser—artists who bucked industry norms.

Read an early piece of journalism on country music

This 1904 Harper’s Weekly article from Emma Bell Miles offers an early example of country music criticism. Miles traces the music’s roots to the mountaineers who pioneered it. It’s a famous piece for music writers: Miles saw a phenomenon building in the hills long before any major record label.

In 1998, Billy Bragg and Wilco recorded unreleased songs penned by Woody Guthrie.

Bob Dylan considered Woody Guthrie a foundational influence, a sentiment he immortalized in his 1962 recording 'Song to Woody.'
