"Harnoncourt's recording made in 1968 reveals a profound insight into the musical style of this time and his thoughts on recording techniques particular to this work make interesting reading.
His singers, including Lajos Kozma in the title role, the juicy bass of Nikolaus Simkowsky as Caronte and the more familiar and fluid voice of Nigel Rogers bring much sensitive expression to the unfolding drama.
The variety of continuo intstruments accompany discreetly and with stylish simplicity, helping to emphasize and enhance the text. There is much to appreciate in this undoubted achievement though the predominance of recitative without the visual stimulation of a live production makes rather dry listening at times."
