The German baritone is in demand worldwide, collaborating with ensembles such as the NHK Symphony Orchestra, Staatskapelle Dresden, Philharmonia Orchestra, Vienna Symphony, Akademie für Alte Musik Berlin, Zürich Tonhalle Orchestra, Academy of Ancient Music, Les Violons du Roy, Seattle Symphony, and multiple BBC orchestras. He has performed in recital at major festivals—among them those of Schleswig-Holstein, Edinburgh, and Ravinia—and has been heard at such important venues as Festspielhaus Baden-Baden, Amsterdam’s Concertgebouw, Hamburg’s Elbphilharmonie, and Paris’s Musée de Louvre. Working closely with pianists James Baillieu and Graham Johnson, Appl is a regular recitalist at London’s Wigmore Hall and the Schubertiade Hohenems and Schwarzenberg. The baritone, who began 2021/2022 as Harlekin/Ariadne auf Naxos at Barcelona’s Gran Teatre del Liceu, portrays Mozart’s Papageno/The Magic Flute later this season at Dresden’s Semperoper and appears in recital in Barcelona, Paris, and Berlin. Earlier in 2021 he sang a staged version of Bach’s St. John Passion at Paris’s Théâtre du Châtelet. Recent highlights also include his first Guglielmo/Così fan tutte with London’s Classical Opera Company and his Philadelphia Orchestra debut in Bach’s Mass in B Minor. Among the major releases in Appl’s growing discography are a live recording of Schubert lieder from Wigmore Hall and his first solo disc for SONY Classical, “Heimat,” which won the prestigious Prix Dietrich Fischer-Dieskau (Best Lieder Singer) at the 2017/2018 Académie du Disque Lyrique Orphées d’Or. Appl recently released discs of Sibelius’s Kullervo with the BBC Scottish Symphony and works by Bach with both Concerto Köln and the Berlin Bach Soloists.
