The fresh, youthful quality of Sieden’s voice perfectly matched the music of Mozart’s early Exsultate Jubilate. She sang the quick melodic lines with a tightly focused voice, effortless virtuosity and joyous buoyancy that recalled the early Mozart instrumental concertos with which this work is often compared. In the rapid notes of her coloratura singing, there was neither icy precision nor the virtuoso intensity of someone desperate to get through the notes, just confident mastery and pleasure in the music.
In the concert aria Vorrei spiegarvi, oh Dio! Sieden produced smoothly ornamented melodies and melting pianissimo melodies at the top of her register. In No, no che non sei capace, she gave a performance of fiery virtuosity in the passionate, rapid-fire coloratura. – South Florida Classical Review
