She gained notable critical acclaim as “the stunning voice of operatic isolation” for a series of “viscerally powerful” (The Times) performances of La Voix Humaine; following a streamed performance for Grange Park Opera and a video performance specially recorded under lockdown conditions for Welsh National Opera, which earned her Best Actress at the Welsh Theatre Awards, she brought Poulenc’s solo tour-de-force in a triumphant return to London’s Wigmore Hall, with Opera Today praising her “thorough assimilation of both text and music and the intelligence of her delivery. Her intonation is flawless, and her diction perfectly clear […] it is the very unvarnished quality, an honesty of expression, that is perhaps her greatest asset. Such is her portrayal that one watched mesmerised by something excruciatingly real…”
