Dolores O'Riordan, frontwoman of the '90s Irish grunge trio The Cranberries, passed away Monday (January 15). She was 46.

In a statement provided to BBC by the late musician's publicist in the wake of O'Riordan's passing, it was understood that the vocalist was last known to be in London for a studio gathering with the band — consisting of siblings Mike and Noel Hogan — though the circumstances surrounding the cause of her death have not been released.

“No further details are available at this time,” O’Riordan’s publicist told the publication. “Family members are devastated to hear the breaking news and have requested privacy at this very difficult time.”

The Cranberries first rose to international notoriety after the success of their 1993 debut album, Everybody Else Is Doing It, So Why Can't We?, which went on to surpass 40 million record sales and produced well-known singles like "Linger" and "Dreams."

The troupe followed through on their achievements with the release of their second record No Need to Argue in 1994, spawning the group's most lauded hit to date, "Zombie," which became a No. 1 hit in five countries.

O'Riordan is survived by her three children — Taylor, 20; Molly, 16; and her 12-year-old daughter Dakota.
