Valerie Carter, singer-songwriter and backup singer for many hit records has passed at the age of 64.

According to the Tampa Bay Times, Carter passed away on March 4th of a heart attack in her home in St. Petersburg, Florida. Carter’s sister Janice told the paper that her younger sibling had heart issues for years.

Carter released a handful of solo albums over the years, starting with 1977’s Just a Stone’s Throw Away, which included the single “O-o-h Child,” which was used in the 1979 movie Over the Edge. But she was best known as a backing singer on records by Jackson Browne, Don Henley, Linda Ronstadt and James Taylor.

Her songs were recorded by many big names and bands including Judy Collins, Earth, Wind & Fire, and Jackson Browne.

Several of the artists Carter worked with over the years paid tribute to her over the weekend following her death, including Taylor, who wrote “We were the lucky ones, who worked (played) with Valerie Carter over the long arc of her creative career.” (Taylor showed up when Carter graduated from a court-mandated drug program in 2011, following a 2009 arrest for possession.)
