O'Riordan's PR agency confirmed her passing a statement, noting that she was in London for a short recording session.
The statement reads, "Irish and international singer Dolores O'Riordan has died suddenly in London today. She was 46 years old. The lead singer with the Irish band The Cranberries, was in London for a short recording session. No further details are available at this time."
O'Riordan's representatives added, "Family members are devastated to hear the breaking news and have requested privacy at this very difficult time."
As of press time, her cause of death is not yet known.
Born in Limerick, Ireland, in 1971, O'Riordan auditioned for the Cranberries (then called the Cranberry Saw Us) after responding to an advertisement in search of a female vocalist. After changing their band name, early demos caught the attention of press and the recording industry, leading the band to sign with Island to release their first major label EP Uncertain in 1991.
The band delivered their first full-length Everybody Else Is Doing It, So Why Can't We? in 1993, which featured singles "Linger" and "Dreams." The band delivered their sophomore LP No Need to Argue in 1994, which featured the O'Riordan-penned mega hit "Zombie."
The Cranberries then released To the Faithful Departed (1996), Bury the Hatchet (1999), and Wake Up and Smell the Coffee (2001) before going on hiatus in 2003. During that time, O'Riordan released two solo albums of her own, delivering Are You Listening? in 2007 and No Baggage in 2009.
The band reunited to tour North America and Europe in 2009, releasing their sixth LP Roses in 2012. They delivered the compilation LP Something Else last year, which featured acoustic and orchestral versions of 10 singles, in addition to three new tracks.
In May of last year, the band cancelled tour dates in both Europe and North America due to a back problem. O'Riordan had also been diagnosed with bipolar disorder in 2015.
O'Riordan previously lived in Canada, north of Peterborough, ON, with her now ex-husband and music manager Don Burton. The couple had three children together but separated in 2014. The singer had recently travelled to Toronto over the holiday to visit her children.
Following the news of O'Riordan's passing, many have taken to social media to pay tribute and express their condolences. You can see some of those posts down below.
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 (@The_Cranberries) January 15, 2018

My first time hearing Dolores O'Riordan's voice was unforgettable. It threw into question what a voice could sound like in that context of Rock. I'd never heard somebody use their instrument in that way. Shocked and saddened to hear of her passing, thoughts are with her family.— Hozier (@Hozier) January 15, 2018
