This is from the beginning, at the 1989 BBC Cardiff Singer of the World Competition, when he was up against Bryn Terfel. Yeletsky's aria from Tchaikovsky's Pikovaya Dama was one of those things Hvorostovsky sang like no-one else - the vintage cello of a baritone voice just loved those rising scalic phrases, and the breath control was always extraordinary. It was the first thing I thought of today, hearing the awful if expected news (he was four months younger than me). Tomorrow I'll turn to an Arts Desk tribute and listen to a lot more (the Russian folk songs disc, Verdi as well as more Tchaikovsky) when I have the time.
Update (23/11) My Arts Desk homage is here, with excerpts from a 1992 interview for Gramophone and two more YouTube clips. My thanks to Cheryl Madden over on LinkedIn for citing the folksong 'Nochenka' as her favourite Hvorostovsky number - unaccompanied, he is at his nuanced best.
