In April 2020, Dix contracted COVID-19 that developed complications and required her to be hospitalised; she was featured in media outlets talking about using her operatic training to rehabilitate her body post infection.[17]
For many years Dix has understudied roles at the Metropolitan Opera in New York, making her main stage debut in Verdi's Falstaff as Alice Ford.[18] In March 2023, due to the last-minute withdrawal of Sonya Yoncheva, Dix gave her Metropolitan debut as Norma (Bellini).[19] An audio recording of the performance, which includes Michael Spyres as Pollione and Ekaterina Gubanova as Adalgisa and is conducted by Maurizio Benini, is available for streaming at Met Opera on Demand.[20]
Critical reception
Her portrayal of Elizabeth I in Roberto Devereux received positive reviews. Rob Holdsworth said she was "The most exciting voice since Sutherland"[21] and The Age wrote:
The Australian-born soprano sang one of opera's most demanding roles flawlessly, from florid coloratura to (literally) high drama via ravishingly delicate pianissimos. But what was most extraordinarily impressive was her acting, vocally and physically, by turns a termagant, fragile, nervous, regal, vulnerable – a woman in love with a man 30 years younger, rightly doubting that it is requited. Dix gets 8 out of 5 stars.[22]
In Wagner Dix seems to me more impressive, personable and occasionally witty in this demented role which veers from Beethoven's Leonore – to bel canto heroine and even French comic minx .The gleaming if slightly metallic middle register gives great focus to intelligent recitative, and all the top notes work for her.[23]
Helena Dix is jaw-dropping as Lady Macbeth, spitting her lines with palpable venom as she pushes her hapless husband on a path towards glory – and death. She's a force of nature, her powerful soprano freezing the blood and catching fire all at once. And in that scene, she's tremendous, scrubbing at her imaginary bloodstains with such impassioned madness it seemed like she was going to lose a finger.[15]
