Part 4

Tim Rhys-Evans presents highlights from the remaining five competitors' performances in this opera singing competition. Contestants from Switzerland, USA, Belarus, South Korea and Canada perform a range of famous arias by composers including Mozart, Verdi and Puccini.

The winner of this round will join the three winners who have already secured their place in the final. Drama will be high as one wildcard will be announced to complete the line-up.

Soprano Elin Manahan Thomas and tenor Jeffrey Lloyd Roberts will be on hand with their views on all of the performances while Josie D'Arby reports on the singing events that are happening all around the Welsh capital.
