Petroc Trelawny and Josie d’Arby host the first of two finals taking place in Cardiff this week. The Song Prize was first won by legendary Welsh baritone Bryn Terfel when it was introduced thirty years ago in 1989. For this final, the orchestra has been replaced by a piano as five singers aim to impress the expert panel of judges in the intimate and demanding discipline of ‘art song’ or lieder. On hand to discuss their performances is Welsh bass-baritone Neal Davies who won the prize in 1991 and leading vocal coach Mary King.
