"Son interprets the title role with considerable passion, both vocally and dramatically. Her Act II aria, “Vissi d’arte”, is a showstopper in which her ringing, agile soprano and expressiveness peak. Throughout this act she gives her all to convey Tosca’s fear, grief and rage in a space that is the opposite of intimate."

(Patricia Maunder, Limelight)

“Karah Son is exquisite as Cio-Cio-San, capturing her innocence, as well as her naïve, unshakeable faith in her “husband.” Vocally, she weaves spells with her silvery, graceful soprano, sending shivers down the spine as she soars into her high register and pangs to the heart in her final distress. Her rendition of “Un bel dì, vedremo” (One fine day) is a musical highlight among many."

(Jo Litson, Limelight)

“Karah Son, first and foremost, is utterly stunning as Cio Cio San (Butterfly). She is convincing as the impetuous, naïve, young girl who becomes absorbed by a fantasy romance and holds on fast until the devastating moment of undeniability. Son’s voice is searing and her rendition of opera’s most coveted soprano aria, “Un bel di, vedremo” (“one fine day we’ll see”) is breathtaking. "

“Perfect casting as the impetuous and tragic Butterfly, Karah Son acted with assurance and achieved a consistently beautiful vocal tone throughout. Her superb rendition of One Fine Day provided one of many vocal highlights during the evening.”

“Karah Son’s Desdemona had something close to a perfection of beauty in the sound with rich colour, soft finish and quiet poised presence to match. After the first three acts of male intrigue, her Willow Song and Ave Maria in Act IV were the musical centre of the work for their still moments of quiet simplicity, comely melodic shape and poignant expressiveness.”

(Peter McCallum, The Sydney Morning Herald)

“Fresh from their success as Calaf and Liu in Opera Australia’s Turandot, South Koreans Yonghoon Lee and Karah Son triumphantly returned to the Sydney Opera House for Verdi’s tale of love destroyed by jealousy. Son was equally compelling, expressing Desdemona’s love and sorrow with beautifully rounded soprano notes, and carefully considered and executed vocal dynamics – as well as physical stillness and graceful gestures. In a consistently excellent performance, her poignant Act 4 double aria was particularly exquisite”

“Karah Son, the Korean born, Italian trained soprano was an enchanting Mimi. Passionate when well, fragile in her illness. A beautiful voice, clean and clear hitting her notes beautifully.Her previous roles for OA were Asian characters, Cio-Cio San in Madama Butterfly and Liu in Turandot. This was her first “Western “ role. May there be many more.
