LAS VEGAS  — B.B. King believed anyone could play the blues, and that “as long as people have problems, the blues can never die.”

But no one could play the blues like B.B. King, who died Thursday night at age 89 in Las Vegas, where he had been in hospice care.

Although he kept performing well into his 80s, the 15-time Grammy winner suffered from diabetes and other problems. He collapsed during a concert in Chicago last October, later blaming dehydration and exhaustion.

For generations of blues musicians and rock ’n’ rollers, King’s plaintive vocals and soaring guitar playing style set the standard for an art form born in the American South and honored and performed worldwide. After the deaths of Howlin’ Wolf and Muddy Waters decades ago, King was the greatest upholder of a tradition that inspired everyone from Jimi Hendrix and Robert Cray to the Rolling Stones and Eric Clapton.
