“…there is splendidly committed teamwork in this taut production, with Gerard O'Connor hilariously ruling the 'rude mechanicals' as the stentorian Bottom.”
Bottom: A Midsummer Night’s Dream / Opera Ireland / Sunday Times

"Galway born bass, Gerard O'Connor provided a powerhouse performance as Mephistopheles..."
Mephistopheles: Faust / Opera Ireland / Sunday Business Post

“…Gerard O’Connor’s melancholy Parson–doubling–Badger — the performance of the evening, I thought.”
Parson / Badger: The Cunning Little Vixen / Opera Northern Ireland / The Times

Benoit & Alcindoro: La bohème / Opera Ireland / Opera

“...Gerard O’Connor as music master Don Basilio is a comic presence with a slightly more commanding air about him. His voice gives authority to any role, and it was a pleasure to hear him in this context.”
Don Basilio: The Barber of Seville / OTC, Dublin / Belfast Newsletter

"Gerard O’Connor’s Don Basilio produced a well-rounded tone in his stentorian ‘La calumnia’...”
Don Basilio: The Barber of Seville / OTC, Dublin / Opera

“As Boris he is a commanding and fearsome presence, achieved in equal measure through his physique and voice. This was an opportunity for a major leading role upon which O’Connor has capitalized to the fullest and to the great benefit of the production.”
Boris: Lady Macbeth of Mtsensk / Opera Ireland / The Irish Examiner

“Central to its success was the performance of Gerard O’Connor as a truly awful Boris, a witless brute and lecher after his son’s wife. He sent shivers down the spine with lines like "If I were ten years younger.”
Boris: Lady Macbeth of Mtsensk / Opera Ireland / The Irish Times

“The lecherous father–in–law, Boris, was a tour de force presented in the dark brown bass of an inspired Gerard O’Connor.”
Boris: Lady Macbeth of Mtsensk / Opera Ireland / Sunday Business Post

“…the other outstanding performance was that of Ireland’s own Gerard O’Connor as the brutal, hypocritical father–in–law Boris Ismailov: his big, resonant black bass is ideal for the role.”
Boris: Lady Macbeth of Mtsensk / Opera Ireland / Sunday Times

“As Boris, her powerful father–in–law, Gerard O’Connor dominated proceedings, musically and physically. It was a remarkable performance, catching the power and ambition of the man and the hint of a personal desire for his recalcitrant daughter–in–law was one of the production’s many felicitous touches. O’Connor has developed into an outstanding bass, acting with terrifying conviction and singing his music with remarkable assurance and power.”
Boris: Lady Macbeth of Mtsensk / Opera Ireland / The Sunday Tribune
