“Doyle’s declamatory way with the opening scenes gives way to a fierce, expressive lyricism as guilt and isolation begin to corrode both Macbeth’s mind and his sense of his own integrity”
Tim Ashley, The Guardian ****

“Grant Doyle sings the role with such unforced strength and, in his closing aria, stylish musicianship that audiences round the country should count themselves lucky to have him”
Richard Fairman, Financial Times ****

“Grant Doyle finds real depth of feeling for Macbeth's despairing final moments” Nick Kimberley, Evening Standard ****

“Grant Doyle combines Macbeth’s monstrous pessimism, his courage and agonising moments of self-knowledge with disarming directness. This is a commanding performance, and Doyle has the vocal resources and dark Italianate inscrutability to give the role full measure”
Peter Reed, Classical Source

“Grant Doyle was a forceful, multi-faceted Macbeth, capturing the early torment and moral decline with subtlety. Vocally he was imposing... he brought an appropriate sensitivity and drama to key moments, most noticeably the banquet scene and the finale”
Dominic Lowe, Bachtrack ****

“Grant Doyle rages and rampages as Macbeth”
Claire Seymour, Opera Today

“Grant Doyle carries the role with a vibrant, forthright tone and, retaining an air of humanity, fills his final aria with regret rather than self-pity”
