Singer-songwriter Marianne Faithfull, an iconic figure in the British Invasion pop culture movement of the 1960s, has died.

Her label, Republic Media, issued a brief statement Thursday. It read, in full: “It is with deep sadness that we announce the death of the singer, songwriter and actress Marianne Faithfull. Marianne passed away peacefully in London today, in the company of her loving family. She will be dearly missed.”

Faithfull was 1978, according to The Associated Press.

Her impact in the 1960s was considerable: She had a high-profile romance with Mick Jagger, but also was a successful singer-songwriter in her own right, with British Top 10 singles including “As Tears Go By,” “This Little Bird” and “Summer Nights.” She appeared in films and co-wrote and/or inspired several Rolling Stones songs.

After her personal life and career were derailed by heroin addiction in the early ‘70s, she rebounded as an artist. Her 1981 album “Broken English” earned her a Grammy nomination for Best Female Rock Vocal Performance, and in later decades she was widely regarded as one of the most influential women in rock, based on her musical and literary output.

Reaction to her death also bore out her status. Keith Richards offered “My heartfelt condolences to Marianne’s family!” on x.com, saying “I’m so sad and will miss her.” On the same platform, Jagger said, “I am so saddened to hear of the death of Marianne Faithfull. She was so much part of my life for so long. She was a wonderful friend, a beautiful singer and a great actress. She will always be remembered.”

Appreciation was hardly limited to artists of one era or genre. Faithfull sang backing vocals on Metallica’s “The Memory Remains” in 1997 and the band did not stint on its praise. Drummer Lars Ulrich posted on the band’s x.com account: “Thank you, Marianne … For the good times For your kindness For the great stories For your fearlessness …And the biggest Thank You and F— Yeah for your incredible and unique contribution to our music, and for always being so willing to join us in performing it…and partake in the ensuing shenanigans! Rest in Peace.”

Rolling Stone’s tribute described the unique evolution of Faithfull’s voice and persona. When her first single became a hit “she was only 17 and sang in a voice that sounded frail and very young … [but] imbued the song and its lyrics about feeling left out with a conviction that would point the way toward her later work.”

Her “second act” that began in the ‘80s made her “a singer-songwriter of earned hard wisdom,” said the story, and her deeper voice – a result of damage from illness and drug abuse, suited her embrace of punk rock and more mature material.

Faithfull wrote three memoirs: “Faithfull: An Autobiography;” “Memories, Dreams & Reflections;” and “Marianne Faithfull: A Life on Record.”
