Naomi Judd has passed away. She was 76 years old.

The cause of death was not given, other than a reference to “mental illness”.

The Kentucky-born singer and member of Grammy-winning duo The Judds was the mother of stars Wynonna and Ashley Judd.

Naomi’s daughters announced the news of their mother’s passing on Saturday, April 30. The girls provided the statement to The Associated Press.

In the statement, they said, “Today we sisters experienced a tragedy. We lost our mother-in-law to mental illness. We are broken. We navigate deep mourning and know that as we loved her, she was loved by her audience. We are in uncharted territory.

The Judds are also set to be inducted into the Country Music Hall of Fame on Sunday, May 1.

Together, the mother and daughter performers landed 14 No. 1 hit songs during careers that spanned some three decades. Following their rise to the top of the country charts, Naomi had to step back from the spotlight after doctors diagnosed her with hepatitis.

The Judds’ hits include the 1990 song “Love Can Build a Bridge”, the 1984 song “Mama He’s Crazy”, the 1988 song “Turn It Loose” and many more.

Originally from Kentucky, Naomi worked as a nurse when she and her daughter Wynonna started singing professionally together. Their harmonies were appreciated, especially when combined with acoustic music and bluegrass. They were out of competition.

The Judds released six studio albums and one EP from 1984 to 1991 and won nine CMA Awards and seven from the Academy of Country Music. The group has also won five Grammy Awards.

Together they sang about family, marriage and the virtue of parents who stick together.

Naomi is survived by her husband (and fellow singer), Larry Strickland, who years earlier was a backup singer for Elvis Presley.

Earlier this month, the mother-daughter duo announced a return to the road for the first time in over a decade for The Final Tour. The 10-show series was scheduled to begin Sept. 30 in Grand Rapids, Michigan at Van Andel Arena and run through Oct. 28 at Bridgestone Arena in Nashville.

“What I’m most looking forward to is celebrating Judd’s music with the fans,” Wynonna previously said in a statement about the reunion tour. “Mom and I have had quite the journey over the past 38 years, and the fans have been with us through it all. This tour is a celebration for them.
