Russian baritone Dmitri Hvorostovsky dead at 55

Dmitri Hvorostovsky, the Russian baritone known for his velvety voice, dashing looks and shock of flowing white hair, died Wednesday at a hospice near his home in London, a few years after he was diagnosed with a brain tumor. He was 55. Called "the Elvis of opera" and the "Siberian Express" by some, Hvorostovsky announced in June 2015 that he had been diagnosed with the tumor.
