The double chorus demands of the Sanctus posed no problems and, on the orchestral side, apart from passing lapses in the strings, brilliance was balanced with poetry.
David Hamilton was the first soloist to step forward in the Kyrie, his strained entry steeling one for worse to come.
And it did; the tenor's Ingemisco tamquam reus projected a desperation that jarred with Verdi's recurring requests for sweetness.
Otherwise, Morag Atchison, Catrin Johnsson and Joel Amosa were a musicianly trio.
If the blend of the two women's voices did not always meld as they might have, Amosa's quiet dignity and beautifully turned lines were a constant joy.
