This year the dramatic tenor jon VICKERS celebrates his 25th season at Covent Garden. He started his working life as a businessman, and what makes his transformation all the more surprising is that he claims: ' I had no ambition to be a singer, and in honest truth I have no ambition to be a singer.' In constant demand in all the great opera houses of the world, his ability to reveal what motivates an operatic character has been described by Sir Colin Davis : Jon is a tremendous force. He's the only one who brings those obsessive operatic characters to life: Tristan, Florestan, Peter Grimes and Aeneas in The Trojans.'
