Dolores O’Riordan, the lead singer of the popular Irish rock band The Cranberries, died suddenly on Monday in London, according to her publicist. O’Riordan was in London to do some recording.

The singer’s publicist says that O’Riordan’s family is “devastated,” but that “no further details are available at this time.” A rep from the band stated that she died “suddenly,” but offered no further information.

Her fellow band members expressed their sadness on the band’s Twitter, saying “we are devastated on the passing of our friend Dolores.” According to TMZ, the Cranberries reunited in 2009, and were planning a tour last year, but ended up canceling because of Dolores’ back pain.

We are devastated on the passing of our friend Dolores. She was an extraordinary talent and we feel very privileged to have been part of her life from 1989 when we started the Cranberries. The world has lost a true artist today.

The Cranberries were formed in 1989 and a year later, O’Riordan became the band’s lead singer after the original singer bailed. The group reached mainstream success with the song, “Zombie,” in 1994, which led to worldwide popularity and new life for earlier songs like “Linger” and “Dreams.”
