The Cunning little vixen

New England Conservatory, 2016

Rafael Helbig-Kostka was a prim Schoolmaster clad in academic robes, and whose character-determined inhibitions happily did not extend to his fluid, lustrous tenor.

new england conservatory, 2015

Rafael [Helbig-Kostka] (tenor) as Pylades was simply marvelous with a lean, smooth sound that soared above the strings in his Act II aria.
— Laura Stanfield Prichard, The Boston Music Intelligencer

Cosí fan tutte

New England conservatory, 2015

As Ferrando, tenor Rafael [Helbig-Kostka] was the vocal standout: his honeyed tones and sophisticated Italianate command evoked the era of Gigli and Martinelli, most movingly in “Un’aura amorosa.” He is a man to be watched.
— Lee Eiseman, publisher; The Boston Music Intelligencer
