Dennis O'Neill is a Welsh tenor.
He has been one of the hardest working tenors on the world stage over a thirty year period and he has many achievements to his credit.
As a young singer he covered for singers like José Carreras, Plàcido Domingo, and Carlo Bergonzi finally getting a big break when he sang Flavio in Norma in 1979 with Shirley Verrett at the Royal Opera.
Another break he claims was one of the highlights in his career happened when he was invited to sing Foresto in Attila at the Royal Opera with Ted Downes in Elijah Moshinsky's production. It was a big success.
Since 1979, Dennis O'Neill appeared in nearly every season at the Royal Opera House for over twenty years and his distinguished career has included many major appearances.
Known particulary for his Verdi roles he remembers he was once warned never to touch Verdi. Ironically his very first major success happened to be Alfredo in La Traviata and since then he has sung Verdi at Munich, Vienna, the Met, Chicago, Berlin, Sydney, Paris and in many other opera houses around the world.
For the Royal Opera alone, he has sung Macduff, the Duke of Mantua, Gustavus, Don Carlo, Foresto, Radames, Otello, Jacopo, Aroldo, Ismaele, Carlo VII and Alfredo, and elsewhere his roles have included Manrico, Gabriele Adorno, Oberto and of course, the Verdi Requiem.
In the 80's he had an enormously popular television series and his recordings remain leading examples of his art and in 2000 he was awarded the CBE for his services to opera.
