Unbelievably, in 2013 it will be 30 years since the Finnish soprano and now opera legend Karita Mattila won the very first competition. Following her win in 1983, she exploded onto the international scene, and has remained at the top of her profession ever since.

In the archive section of the website, you can remind yourself of her performance and those of many of the other 362 talented performers who have competed in Cardiff throughout the competition's history.

Karita Mattila was interviewed in 1991 about the doors that suddenly opened to her following her win – first Brussels Opera, then Vienna and the Met soon followed. You can watch her interview, which is also in the archive section.

Karita Mattila

Valentina Nafornita, the Moldovan soprano who was both the choice of the 2011 jury and audience for two prizes, is on the same trajectory as Karita Mattila was following her win.

Prior to competing in Cardiff, Valentina's career had been confined to Romania, but after the competition she joined the Vienna State Opera, where roles she has performed include Musetta, Clorinda, Oscar and Gilda and recently returned from a tour of Japan with the company for Le nozze di Figaro and Die Zauberflöte. She has just made her debut at Teatro alla Scala, Milan as Gilda, under the baton of Gustavo Dudamel.
