“The greatest pleasure lies in the singing of the minor character, Arbate, stylish and sweet in the voice of the Icelandic mezzo soprano Sigridur Osk Kristjansdottir.”
“Sigrídur Ósk Kristjánsdóttir's mezzo is more metallic in timbre, with a bell-like resonance … she settled to deliver a ravishing account of Haydn's Arianna a Naxos cantata, charting Ariadne's descent into madness with taste and sensitivity.”
“Remember her name.”
“She is a magnificent singer. As one might expect, the music is immensely dramatic, and Sigríður conveyed it to the audience with great impact. Her voice was at once clear and expansive, and her interpretation powerful and full of dark emotion.”
“The sunny mezzo soprano”
“The jewel at the centre of the afternoon was a fine performance of Haydn's Arianna a Naxos, sung from memory by the Icelandic mezzo soprano Sigridur Osk Kristjansdottir … This was as good a performance as I have heard, temperamentally mature, yet softened by a youthful voice.”
Ave Maria by William Gomez at Skálholt Cathedral on the 20th of July 2024.

Annual Christmas concert
Sígild jól — "Classical Christmas" — is Sigríður Ósk's annual Advent concert: a quiet evening in which classical Christmas repertoire, Icelandic carols and art song sit side by side.
Sigríður Ósk produces the concert herself and invites a different group of singers and instrumentalists each year, so every edition has its own character. The concerts are held in Seltjarnarneskirkja, a church chosen for its fine acoustics.
The next concert is on Friday 4 December 2026 at 8 pm in Seltjarnarneskirkja, marking the 10th anniversary of Sígild jól. For the occasion, composer Bára Grímsdóttir is writing a Christmas song especially for the concert. Performers: Sigríður Ósk, Sigrún Hjálmtýsdóttir, Gissur Páll Gissurarson, Árni Heiðar Karlsson, Matthías Stefánsson and Júlía Mogensen.
