Dolores O'Riordan, the lead singer of the Irish band The Cranberries, has died suddenly at age 46.

O'Riordan defined the sound of The Cranberries — with hit songs like "Linger," "Salvation" and "Zombie." She brought a particularly Irish inflection to pop charts around the world, particularly in the 1990s.

Her publicist confirmed that O'Riordan died suddenly Monday in London, where she had been recording. No other information about her death was immediately available.

"To all those who follow and support Irish music, Irish musicians and the performing arts her death will be a big loss," Irish President Michael Higgins said, according to The Irish Times.

O'Riordan was born Sept 6, 1971, and grew up in the Ballybricken area of County Limerick. She was just 18 years old when she auditioned to be a singer with The Cranberries, a group founded in 1989 by two brothers, bassist Mike Hogan and guitarist Noel Hogan, along with singer Niall Quinn and drummer Fergal Lawler as The Cranberry Saw Us. Quinn left the band within a year, and O'Riordan auditioned to be its new singer.

In 1993, The Cranberries' debut album, Everybody Else Is Doing It, So Why Can't We? went to No. 1 in the U.K. and to a Top 20 spot on the Billboard 100. The group's following three albums — No Need To Argue, To The Faithful Departed and Bury The Hatchet — also hit the Billboard Top 20.

O'Riordan was the band's primary lyricist and often wrote The Cranberries' music as well. She possessed a singular, instantly recognizable voice that had a smoky hue in full cry, but which she could also hone into a sweet, delicate tone that evoked centuries of Gaelic folk tradition.

The Cranberries broke up in 2002, when O'Riordan left the band — but not before they had sold some 35 million albums worldwide. "I retired, really," the singer told WXPN's World Cafe in 2007, saying that by the time the group's fourth album, Bury The Hatchet, was released in 1999, the band had "burned out" after having achieved enormous success so early.

"I didn't know if I'd come back to the music world, the entertainment world. I'd spent so long with The Cranberries. I was a teenager when the band broke — I spent many, many years touring. I have four kids, so I just wanted to prioritize my family and just be a person."

But O'Riordan found her way back to music, and released her first solo album, Are You Listening?, in 2007, followed by No Baggage in 2009. That same year, however, The Cranberries reunited, and toured with a mix of old hits, songs from O'Riordan's solo work, and new tunes. The band had been touring internationally in 2017, but in July the band announced that O'Riordan was forced to cancel due to ongoing problems with her back.

Among those marking their mourning on social media are the band Duran Duran. (O'Riordan's ex-husband, Don Burton, was a tour manager for Duran Duran.)
