Siberian operatic baritone Dmitri Hvorostovsky's commanding voice is as sturdy as oak. His stage debut outside the Soviet Union came in 1989 at the age of 27, and he's gone on to master countless dramatic arias and songs at opera houses worldwide. His “Pace non trovo” from Liszt's 3 Sonetti di Petrarca has a sympathetic lyricism that is rare among his voice type; the same quality pervades his arias from Tchaikovsky's Mazeppa, where his stunning agility and tenderness bring the composer's sensational melodies to life.
