Conall O'Neill effectively conveyed Lorenzo's anger with the bloodlust of the Capuleti. His well rounded basso cantante made one regret that he didn't have more to sing - Martin Wheeler (Opera News) - Wexford Festival Opera (2022)
“Amongst a universally strong supporting cast, I’ll single out [...] Conall O’Neill (Colline) for a powerful bass voice and a knockout Vecchia zimarra” Bachtrack (David Karlin) (2019)
"...six equals who together smashed the Mechanicals’ scenes. No praise is high enough for their efforts." Bachtrack (Mark Valencia) (2018)
