King of the Blues, B.B. King, died late Thursday at home in Las Vegas. He was 89.

His attorney, Brent Bryson, told The Associated Press that King died peacefully in his sleep.

Although he continued to perform well into his 80s, the 15-time Grammy winner suffered from diabetes and had been in declining health during the past year. He collapsed during a concert in Chicago last October, later blaming dehydration and exhaustion. He had been in hospice care at his Las Vegas home.

For most of a career spanning nearly 70 years, Riley B. King, aka Blues Boy, aka B.B., was not only the undisputed king of the blues but a mentor to scores of guitarists, who included Eric Clapton, Otis Rush, Buddy Guy, Jimi Hendrix, John Mayall and Keith Richards. He recorded more than 50 albums and toured the world well into his 80s, often performing 250 or more concerts a year.

King played a Gibson guitar he called Lucille.

B.B. King had 15 biological and adopted children. Family members say 11 survive.

Funeral Services are pending.
