Russian opera superstar - dubbed the 'Elvis of opera' - loses battle with cancer.

Kanal24 reports citing Classic FM that the singer died this morning at the age of 55. He had been receiving treatment at London’s Royal Marsden Hospital since June for a malignant brain tumour.

Hvorostovsky cancelled all performances after the tumour seriously affected his sense of balance. He made a final appearance on 5 July in a recital at the Russian ambassador’s residence in London, when he sang arias by Borodin, Glinka, Tchaikovsky and Rachmaninov.

Tall, with a shock of prematurely silver hair, Hvorostovsky was lauded around the world, as well as being listed as one of People magazine's 50 most beautiful people – a rarity for a classical musician. Elle magazine described him as the ‘Elvis of opera’.

Born in Siberia on 16 October 1962, Hvorostovsky sang in a heavy metal before making his debut at the Krasnoyarsk Opera House, in Verdi’s Rigoletto. He went on to win First Prize at both the Russian Glinka Competition in 1987 and the Toulouse Singing Competition in 1988.

Hvorostovsky came to international prominence in 1989 when he won the Cardiff Singer of the World competition, controversially beating local favorite Bryn Terfel in the final round. Hvorostovsky’s performance included Handel's ‘Ombra mai fu’ and an extrat from Verdi's Don Carlos. “I was sure I was going to win until I heard Bryn Terfel sing Wagner - then I was not so sure,” he said at the time.

His operatic debut in the West was also in 1989 at the Nice Opera in The Queen of Spades (1989). He debuted at La Fenice, Venice, as Eugene Onegin, a success that sealed his reputation, and made his American operatic debut with the Lyric Opera of Chicago in La traviata in 1993.

The baritone went on to sing at virtually every major opera house, including the Met, the Royal Opera House and La Scala Milan. He became especially renowned for his portrayal of Tchaikovsky's Eugene Onegin, a role which The New York Times said he was “born to play.” In recent years his stage repertoire consisted almost entirely of Verdi operas such as Un ballo in maschera, La traviata and Simon Boccanegra.
