Elizabeth II, longtime Queen of the United Kingdom, died at 96 on Thursday (Sept. 8), as PopCrush reported.

Rock and metal musicians worldwide are now mourning the loss of the British ruler and cultural figurehead.

Queen Elizabeth II presided over the U.K. for seven decades, The New York Times noted Thursday, making her the world's longest-reigning monarch. She died peacefully at her Scottish holiday home, Balmoral Castle, surrounded by the Royal Family, who subsequently confirmed the death.

Charles III, former husband of the late Princess Diana and now King of the U.K. after the death of his mother, said in a statement that Elizabeth's death was a "moment of the greatest sadness."

The Queen had showed declining health since the death of her husband, Prince Philip, last year. This summer, she stayed primarily at Balmoral instead of her usual residence at Buckingham Palace.

Charles added, "We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother. I know her loss will be deeply felt throughout the country … and by countless people around the world."

Those in rock and metal shared similar sentiments.

Metal showman Ozzy Osbourne, who's currently moving back to his native England, said on social media, "I mourn with my country the passing of our greatest Queen. With a heavy heart I say it is devastating the thought of England without [her]."

Osbourne wasn't the only Black Sabbath alum to offer condolences. Sabbath's Geezer Butler remarked, "Sad to hear of The Queen passing. I remember the street celebrations when she was crowned Queen. Always a staple of growing up in England."

Rock singer Sebastian Bach shared a portrait of the Queen that his late father, the artist David Bierk, had painted. "Cant help but think of Dads painting," Bach said. "Hope the painting is still in good condition. RIP … a leader who brought the whole world together."
