Dyfed Wyn-Evans' operatic work includes appearances for Grange Park Opera, English Touring Opera, Broomhill Opera, and the Buxton Festival, and has performed the role of The Podestat in Bizet's Le Docteur Miracle, one of the most challenging of all baritone roles, at the Voray Festival in Besançon.
British engagements also include Bartolo in Mozart's Le nozze di Figaro for Opera North and Garsington Opera; Collatinus in Britten's Rape of Lucretia at Buxton Festival; and Sacristan (Tosca), Bosun (Billy Budd), Benedict (La Vie Parisienne) and Masetto (Don Giovanni) for Scottish Opera.
It was staged at the Wexford Festival in 1968, the Théâtre Impérial de Compiègne in 1998 and the Buxton Festival in 2006, and recorded by the BBC in Manchester for the Bizet centenary in 1975.
