Aficionados of French (or France-based) opera will warm to ‘Paris, mon amour’ by the Bulgarian soprano Sonya Yoncheva. Schooled in the refinements of Baroque opera by William Christie, she here broadens out into the Romantic repertoire, demonstrating that her rich, malleable timbre, control and sensibility open doors for her across a good range from Massenet to Offenbach, Puccini and Verdi to André Messager. As a sampler of her formidable gifts, this is a sure collector’s item.
