Collin Shay’s supple, rich countertenor brings Ottone, Poppea’s spurned lover, to life

The voices of Ottavia and Ottone (Collin Shay) stood out in particular due to their timbre qualities.

There’s also tender singing from Collin Shay worth praising. His countertenor voice as Ottone brings the opera to a pause with its dazzling textures, particularly when he sings to Poppea, which pulls on your heart strings.
