Bernhard Sieberer studied conducting with Edgar Seipenbusch at the Innsbruck Conservatory, and attended master classes with Sergiu Celibidache in Mainz, Gustav Kuhn in Milan, and Michael Gielen at the Mozarteum Salzburg (funded by the Alban Berg Foundation of Vienna).
Sieberer was formerly principal guest conductor of the chamber choir Jauna Muzika in Vilnius and has been cultural commissioner of the town of Kufstein since 1993.
An ongoing collaboration with the Slovakian chamber orchestra Capella Istropolitana has produced a number of recordings which have been published under the title "...im Gespräch" ("... in conversation").
Bernhard Sieberer has a broad repertoire: it includes choral works from the Renaissance up until the 21st century and orchestral pieces by a variety of composers, ranging from Bach to Bruckner, from Mozart to Mahler, from Beethoven to Britten, and from Purcell to Pirchner.
Sieberer regularly conducts works by Handel, Bach, Haydn, Mendelssohn and Brahms, as well as Bruckner, Orff and Honegger, and also contemporary music.
