Gegham Grigorian made a great contribution in the formation and establishment of a company of soloists under the chief conductor and artistic director Valery Gergiev.

"When he did eventually appear regularly in the West – under the patronage of the conductor Valery Gergiev – he thrilled audiences at Covent Garden, where his portrayal of Lensky in Tchaikovsky's Eugene Onegin was hailed as musical gold by critics, and at the Metropolitan Opera, New York, where he gave a moving account of Herman in The Queen of Spades."

After a concert performance of The Queen of Spades with the BBC Philharmonic in Manchester in 2004, The Daily Telegraph noted how Grigorian "invested every fibre of his being in the obsessed Hermann", while earlier The New York Times had declared that in the same role at the Met his "characteristic concentration produced frequent haunting moments".
