Solo recitals of arias from Handel operas and oratorios are common, so it's a pleasure to hear an album devoted to his duets, particularly when they're performed as well as they are here by soprano Rosemary Joshua and mezzo-soprano Sarah Connolly. Both have had diverse careers, but are known especially for their Baroque roles. Their voices are especially well-matched in weight, and their blend is beautifully warm, but they are each distinctive enough that they retain a strong vocal identity even when singing in close harmony.
