[1][2] Wörner has performed with conductors such as Carl St.Clair, Christophe Coin, Thomas Hengelbrock, Philippe Herreweghe, Tõnu Kaljuste, Sigiswald Kuijken and Helmuth Rilling.
He recorded Bach's solo cantatas for bass such as Ich will den Kreuzstab gerne tragen, BWV 56, for example in 2013 with Ryo Terakado conducting the ensemble il Gardellino.
[4] A review of the "ambitious project" noted: "Wörner's quiet but colorful bass-baritone and reflective attitude toward the text are evocative of the small gatherings in which the music of the Second Viennese School took shape".
Wörner appeared on the opera stage at the Solothurn theatre in the title role of Jean-Jacques Rousseau's Le devin du village, which was recorded conducted by Andreas Reize.
He premiered works composed for him, such as Canticum Canticorum by Marco Sofianopoulo, first performed in the Trieste Cathedral, and Werner Jacob's Lamentatio and Triptychon in St. Sebald in Nuremberg, for the broadcaster Bayerischer Rundfunk.
