What luck to have two of the best counter-tenors coming together on this CD of duets. These duetti are, in fact, a combination of duets, solo and dialogue recitatives and arias, largely composed between 1680 and 1720. In Bononcini's 'Pietoso nume...'the two men blend and synchronise perfectly, both voices shining without eclipsing the other. Jaroussky is given the solo in Mancini's 'Quanto mai...' and sings like a bell throughout. Conti's 'Nightingale' is full of clever musical trills for the continuo,especially at the end. Jaroussky soars on the supporting wings of Cencic and both sing as one when imitating the nightingale's song penetrating the night. Bononcini's'Chi d'amor...'is a slow lament of undulating harmonies, whereas his 'Bella si'...is a display of vocal sprinting by the two men, with much spurting,surging and elbowing. Cencic is awarded the solo in Porpora's'Ecco che...',showing his voice, comfortably in his range, to beautiful effect, with some sweeping arabesques. Marcello's 'Chiaro e limpido' is the highlight of the disc, with richer orchestration. Jaroussky is flamboyant in his solo whereas Cencic is more sedate but shows equal virtuosity. There is an exquisitely flowing duet in which the singers are totally complementary followed by a lament in which Cencic is more anguished - before they gallop off after the beloved in the conclusion. This is followed by a divine and emotional seven minutes of elegant and melodic intertwinig of soprano and alto as abashed admirers. Scarlatti's'Nel cor...'enables both to show off their technical artistry, the voices moving at a brisk pace in parallel and in adroit counterpoint, leaving the listener abruptly stranded in mid-air - a very dramatic end to this collection of colourful and moving duetti.
