Cleo Laine, who was married to and performed with fellow jazz musician John Dankworth, has died, according to the U.K. music venue they'd founded.

The Stables, a charity and venue Laine founded with her late jazz musician husband John Dankworth, said Friday (July 25) it was “greatly saddened” by the news that “one of its founders and Life President, Dame Cleo Laine has passed away.”

I don’t consider myself a jazz singer… I’m a singer of songs,” said the vocal star, who won a Grammy in the Best Female Jazz Vocal Performance category.
