| Review: Die Zauberflöte, Salzburg Festival "Simon O'Neill and Günther Groissböck were a particularly strong pair of Men in Arms, their voices combining mellifluously during their short scene in Act 2" THE OPERA CRITIC 8 August 2005 | 
| Also outstanding was Günther Groissböck as the Nightwatchman, who only spends about six minutes on the stage in this mammoth work but managed to give those minutes a remarkable authority and timbre./Meistersinger Review |
