However, the lead single Zombie was a huge departure from The Cranberries' usual fare - not only breaking into angsty grunge, but drawing on a recent tragedy for a visceral protest song.
The Irish singer was in London for a recording session when she died suddenly at a hotel in the capital's Park Lane on 15 January 2018. As of writing, no further details have been released about her passing.
"A woman in her mid 40s was pronounced dead at the scene".
Police in London are still investigating the singer's "unexplained" death, but they are not treating it as suspicious.
In her hometown of Limerick, residents signed a book of condolence at the city council. But in late December, the singer posted a message to fans on their Facebook page, saying she believed she would be back on stage soon.
She certainly captured the angst of my teenage years.
"She was looking forward to seeing me in the studio and recording vocals". A Spotify spokesperson told Fortune that, since news broke of O'Riordan's passing, streams of The Cranberries' catalogue jumped by a whopping 992%. "On tour it's, like: "'room-service", she said of the comeback. She headed to Canada, where she gave birth to her third child, but The Cranberries reformed in 2009 after getting together for a one-off show. The parish priest from her hometown Friarstown said her funeral would take place in Ireland.
A friend said the singer sounded excited and "full of life" just hours before her death. Fellow Irish boy band star Ronan Keating adds: "Totally shocked at the news about Dolores O Riordan an incredible talent and a lovely soul".
Critics called O'Riordan out for singing in her Limerick accent (which can be strong and hard for foreigners to understand), but she stuck with it ... and it paid off big time!
Tony Das, a well-known musician talks about Dolores' iconic voice and what made him instantly fall in the love with Cranberries, "I would say it was pretty much her voice that made them stand apart from a lot of the stuff happening at the time".
