Fanny Price, Mansfield Park (Dove): ‘Dove’s leading role of Fanny Price was entrusted to History First Class Honours graduate Rebecca MacGregor-Black, a trust she repaid marvellously. (Her performance) …in a Cinderella-like characterisation of a young woman who stands firm against bullies, was pretty well perfect.’ - Donal Hurley, Edinburgh Music Review (2023).

Yniold, Pelléas et Mélisande (Debussy): ‘The excellent Yniold was Rebecca MacGregor-Black’ - Andrew Clark, Opera Magazine (2022).

Johanna, Sweeney Todd (Sondheim): ‘The show’s less twisted romantic coupling is found in Anthony and Johanna, played by Jobim Ffench and Rebecca MacGregor-Black. In addition to their beautiful voices, Ffrench and Black played off each other so well to create moments of true joy in such an ominous show.’ … ‘Ffrench’s ‘Johanna’ is truly a highlight, and Black plays a character worthy of the beauty of the song that bears her name. The pair are enchanting and Black…is a breath of fresh air in the darkness of the production, her wistful performance of ‘Green Finch and Linnet Bird’ will capture your heart’ – The Calliope Arts Journal (2022).

Daphne Stillington, Present Laughter (Noël Coward): ‘Garry Essendine (Marcus Judd)…is in high demand….beautiful young women are constantly arriving at his swanky London home late at night, having forgotten their latchkeys.

One such woman, Daphne Stillington (Rebecca MacGregor-Black), opens the show via a chat on the rotary phone, the centrepiece prop, bringing the audience up to speed. Her nervous energy and sickeningly sweet murmurs into the receiver gain the first laugh of the night, and from there, the energy rarely flags… It is astounding how well each member of the cast is equipped to tackle the high-octane comedy of Present Laughter. Nearly every actor performs with a voice or accent not their own, and…rely on physical comedy and perfect comedic timing to ensure the jokes land.’  - St.Art  Magazine (2023).

Sister Berthe, The Sound of Music (Rodgers): ‘There is so much to enjoy in this stellar production, and there are many standout performances throughout. The songs are extremely demanding, yet Rebecca MacGregor-Black as Sister Berthe handles this with aplomb.’ - Voice Magazine (2024).
