Praised by the Observer as having a voice with 'rich, dramatic potential' and for her clarity of diction as well as her ‘vibrant and bright tones’ by Opera Now, Gráinne Gillis is an Irish-American contralto. She read Music at UCC and graduated from the Bristol Old Vic Theatre School.

Career highlights have included singing Madame Flora in Menotti’s The Medium, the Mother in Hansel and Gretel, and Pierrot Lunaire, all at Grimeborn, working with Sir Peter Hall on a sold-out US tour of As You Like It, and three seasons with Pavilion Opera on Die Zauberflöte, Macbeth and La Traviata respectively.

In 2018/19 she sang Flora in the Olivier award-winning King’s Head Theatre’s production of La Traviata and opened the London Song Festival.  This season also included her one-woman show Mezzo Sings The Bard (which she will reprise at WAF 2022) Hélène in Faust et Hélène, the Old Woman in Candide and La Zia Principessa in Suor Angelica at the Llangollen International Eisteddfod. That summer she also studied with Dolora Zajick and organised a 100-strong chorus for the Women’s March London as part of their ‘Bring The Noise’ event.

In 2019/20 she made her Irish debut as Ruth in The Pirates of Penzance at Cork Opera House, and Vampyrmeister/Suse in Der Vampyr for Gothic Opera (Offie-nominated).

COVID cancellations in 2020 included a national tour of Ireland with Sea Trilogy as well as 1st Magd/cover Klytemnestra in Elektra.
