“…Isolde Roxby’s outstanding Aurora. Pleasantly rounded both vocally and in her characterisation..." Mark Valencia, Bachtrack 
“…The Aurora of Isolde Roxby, by far the biggest role in the opera ... rewarded the confidence placed in her with an account of the role which was generous in its lyricism, poignant in the pain of its self-discovery and completely mesmerising … compelling performance…”
Robert Hugill, Planet Hugill 
“…Isolde Roxby proving exceptional as the Princess as her lyrical yet sensitive soprano is put to excellent use in conveying the various stages that the character goes through across the drama…”
Sam Smith, Music OMH

“…As Tatiana Isolde Roxby makes the right journey from passionate naivete to poised, careful experience. Her ‘letter’ scene was the highpoint it should be, both musically and dramatically…”
Live Theatre UK 
“…admirable performance… Roxby manages the demands of the famous letter scene with warm tones and a real understanding of the emotional torment that leads Tatiana to take such an unconventional step…”

“"…Isolde Roxby has an absolutely stunning voice and gives a wonderful performance encapsulating every part of Tatiana’s innocence and delicate suffering. In the Letter Scene, her performance is filled with sorrow and fragility. This contrasts with the final scenes...Her voice soars as she tells Onegin to leave her alone…”.
“…fine dramatic singing here from Isolde Roxby… expertly navigate a mixture of languages and composers to create consistent characterisation”
The Gizzle Review 
"...Isolde Roxby was a wonderfully ‘genuine’ Cendrillon, delivering the sung and spoken text assuredly, with thoughtful interpretative gestures and a beguiling sweetness of character and tone..."
