Superlatives don't do justice to this priceless and incomparable collection of duets by opera's two most charismatic singers, whose interpretations are brimming with nuance only the truly gifted could capture. However pleasing Cecilia Bartoli's renditions of Cherubino and others in Mozart Arias, the depth of Susanna's emotional life that Bartoli conveys has yet to be even imagined by other sopranos, as she rips through opera's boundaries, creating her very own Fach and threatening the jobs of soubrettes the world over. Once she and Bryn Terfel draw you into their world of stellar, multidimensional creations, there's no escape from pleasure; in their talented hands, recitative becomes as interesting as any aria. The duo's inherent charm overcomes Bartoli's difficulties with German and the dramatic Terfel's with coloratura; however, their sincere attempts to meet these challenges are most endearing. --Barbara Eisner Bayer
