Jun Märkl has long been known as a highly respected interpreter of the core Germanic repertoire from both the symphonic and operatic traditions, and more recently for his refined and idiomatic Debussy, Ravel and Messiaen. His long-standing relationships with the state operas of Vienna, Berlin, Munich and Semperoper Dresden are complemented by his Music Directorships of the Orchestre National de Lyon (2005 - 11) and MDR Symphony Orchestra Leipzig (2012). He appears as a guest conductor with the world's leading orchestras, including: Cleveland Orchestra, Philadelphia Orchestra, NHK Symphony Orchestra, Czech Philharmonic, Munich Philharmonic, Oslo Philharmonic and Tonhalle Orchester Zürich.

Märkl is an accomplished recording artist, having recorded Mahler and the complete Schumann Symphonies live with the NHK Symphony, Dvorák on Telarc, Mendelssohn with MDR and a highly acclaimed nine-disc Debussy set with ONL on Naxos. In recognition of his tenure in Lyon and his hugely successful recordings of French music, he was honoured by the French Ministry of Culture with the Chevalier de l'Ordre des Arts et des Lettres.
