Despite her initial reluctance to play the male role of Enrico, the mezzo-soprano, Anna Bonitatibus, proved to be more than up to the task, putting in an accomplished performance. Her voice has a refined quality, which not only lies easily on the ear, but one Bonitatibus used intelligently to craft a strong vocal portrait of the hero. Her well-grounded mezzo, with its rich dark timbre, shows a wonderful degree of consistency and agility. Throughout the evening she impressed, whether shaping finely articulated recitatives, singing delicately embellished lines with a captivating legato or delivering a sparkling coloratura display, she oozed quality. It was a first-class performance.
