Bach Musica was brave launching this year's season with Bach's St John Passion, with the same work coming up as Auckland Philharmonia Orchestra's annual Choral Classic in August.
On Sunday, before a solid and appreciative audience, Bach's opening chorus augured well.
Male voices could have exhibited a little more vocal spine but Rita Paczian caught the flow and inevitability of the piece, with woodwind players making the most of tangy dissonances. There were some choral shortcomings to come, when the 80 minutes of the Second Part tested stamina.
One of Bach's most effective dramatic touches - the women crying "Whither" in the bass' "Hurry, you troubled souls" - was somewhat diluted by insecure pitching.
More positively, Paczian showed her skill in characterising the many short and punchy interjections that the chorus makes during the grim narrative. The slippery chromaticisms when they claim that no one will be put to death were shivery in their conviction, as was the dark irony of their dance-like greeting to Christ as "Dear King of the Jews".
