Born in Oldenburg, Lehmkuhl received her vocal training with Ulla Groenewold and Hanna Schwarz at the Hochschule für Musik und Theater Hamburg and graduated with distinction.
[1] In 2013, Lehmkuhl returned to Salzburg for a concert performance of Szenen aus dem Leben der Heiligen Johanna by Walter Braunfels, and appeared as Annina in 2014 in a highly acclaimed Rosenkavalier production by Harry Kupfer with Franz Welser-Möst conducting.
[3] In 2016, she first appeared at the Bayreuth Festival as Stimme aus der Höhe in Parsifal; later performances there included Magdalene in Die Meistersinger von Nürnberg from 2017 to 2019,[1] staged by Barrie Kosky with Michael Volle as Sachs and Johannes Martin Kränzle as Beckmesser.
In the first cantata she gives an excellent speech-like account of the recitative 'Nun wird mein liebster Bräutigam', which is followed by a beautifully sung aria 'Bereite dich, Zion'.
"[10] In December 2013, she made her debut with the Berlin Philharmonic in Schumann's Scenes from Goethe's Faust conducted by Daniel Harding,[2] who subsequently invited her to sing Geneviève in concert performances of Debussy's Pelléas et Mélisande with the Swedish Radio Symphony Orchestra in Stockholm and Cologne in March 2015.
