He photographed legends and his pictures have become iconic in American cultural history, but the vast majority of music photographer Jim Marshall’s work has never been seen. Since his death in 2010, Marshall’s estate has been combing through millions of unpublished negatives. This month, a new book and two gallery shows will debut many never-before-published images from Marshall’s coverage of the Rolling Stones 1972 tour, as well as singular portraits of musicians including Johnny Cash, BB King and Joni Mitchell.

VF Culture: Suddenly That Summer.

It was billed as “the Summer of Love,” a blast of glamour, ecstasy, and Utopianism that drew some 75,000 young people to the San Francisco streets in 1967. Who were the true movers behind the Haight-Ashbury happening that turned America on to a whole new age?

Mother Jones: Embedded With the Rolling Stones.

By 1972, Jim Marshall (1936-2010) was already a premier photographer of the golden age of rock and roll. But that year, he got the assignment from Life magazine that would change his career forever: head to Los Angeles and shoot the Rolling Stones putting the final polish on their soon-to-be-canonical double album Exile on Main St. (recorded the basement of a château in the south of France, a process also documented in Stephen Kijak's 2010 Stones in Exile).

CNN: In 1972, the Rolling Stones let it loose for photographer Jim Marshall.

Based on Mick Jagger's serious expression and Keith Richards' focused stare, it was clear the pressure was on.

It was the summer of 1972, and the Rolling Stones were on their American concert tour for their acclaimed "Exile on Main Street" album. But when they were not onstage and rocking out with their fans, they were hard at work remixing tracks at the Sunset Sound studio in Hollywood.

Complex: The Stories Behind Jim Marshall's Iconic Photos.

Nearly 40 years ago, Jim Marshall embarked on The Rolling Stones 1972 tour as their official life photographer. After starting his career in photography in 1958, Marshall gained unrivaled access to jazz and rock artists throughout the 1960s and 1970s. From Jimi Hendrix burning his guitar at the Monterey International Pop Music Festival in 1967 to Bob Dylan kicking a tire around Greenwich Village, Marshall's ability to be in the right place at the right time turned into a vast estate of iconic images.

It’s hard to think about rock n' roll and not think of Jim Marshall. Marshall’s photography has shaped and influenced how we collectively think about some of the greatest musicians of all time: Jimi Hendrix burning his guitar at Monterey, Johnny Cash flipping off the camera at San Quinton Prison, Janis Joplin with a bottle of Southern Comfort and The Beatles walking off the field of their last show—these iconic images were all created by Jim Marshall.
