After news emerged Wednesday (July 26) that the Irish singer Sinéad O'Connor had died at 56, rock and metal musicians started paying their respects and sharing tributes to the late vocalist.

O'Connor, an iconic singer perhaps most visible in the '90s, was well known for her angelic voice and shaved head. Her cover of Prince's "Nothing Compares 2 U" made her a household name.

But infamously, O'Connor gained what might have been her biggest headlines in 1992 when she destroyed a photo of Pope John Paul II during a Saturday Night Live performance to shed light on abuse allegations in the Catholic Church.

Below, see rockers' words for O'Connor.

Among them, The Smashing PumpkinsBilly Corgan said the late singer was "talented in ways I'm not sure she completely understood. But Sinead stands alone as a figure from our generation who was always true to the piercing voice within and without."

Queensryche's Todd La Torre said, "I always admired her stance and her means to protest against the child abuse being protected by the Catholic church."

O'Connor's cause of death was not initially reported. The singer's son Shane Lunny died at 17 in 2022. O'Connor is survived by three other children, Jake Reynolds, Roisin Waters and Yeshua Bonadio.
