Dorothy Kirsten and Franco Corelli come together for a program of operatic arias that captures something of the vitality of the 1960s opera scene. The emphasis throughout is squarely on the voice itself, with both singers given ample space to demonstrate the distinctive qualities that made them such compelling performers. There is little sense of an overarching dramatic design; instead, the recital unfolds as a straightforward celebration of vocal artistry, shaped around their individual strengths.

That directness proves part of its appeal. Without the weight of a larger concept, the focus remains on the awesome power of the human voice.
