"The music, successfully arranged by Werner Steinmetz for chamber orchestra, was performed by the Israel Chamber Orchestra under the baton of Martin Sieghart and its interpretation rich in 'Valeurs'" Kurier, 12.09.2014 ....This is a significant and deeply moving performance of the Tenth; Mahler purists will probably avoid it on principle, others will be rewarde with a telling musical journey. John Broggio and SA-CD.net Sieghart is known for his calm and measured basic tempo, which leaves much room for a passionate expression of emotions. Even in the largest forte, the colorful and intense sound stays harmonious and balanced. Nikkei, Tokyo about Bruckner 4 with NHK-Symphony Orchestra
Martin Sieghart is one of the most versatile musicians of his country. He is a conductor of worldwide demand, a teacher of many successful international students, the founder and director of several festivals, a former longstanding principal cellist of the Vienna Symphony Orchestra, organist, repetiteur and has acted as a moderator on the piano for his own Opera and Orchestral projects.
Sieghart has conducted numerous orchestras, including: Philharmonia Orchestra London, NHK Symphony Orchestra Tokyo, Rotterdams Phiharmonisch Orkest, Tchaikovsky Symphony Orchestra Moscow, the radio symphony orchestras of Berlin, Stuttgart, Cologne and Hanover, the Museum Orchestra Frankfurt and the Residentieorkest Den Haag.
In Austria: Vienna Symphony, Vienna Radio Symphony, Salzburg Mozarteum Orchestra, Tonkünstlerorchester Niederösterreich, Wiener Kammerorchester, Wiener Concertverein.
Further collaborations have led him to symphony orchestras from Malaysia, Macao, Sao Paulo, Santiago di Chile, to the Tokyo Symphony, Japan Philharmonic, Japan Century-Orchestra, Orchestra Filarmonica di Gran Canaria, Orchestra della Toscana, Orchestra Sinfonica Siciliano, Philharmonic Orchestras from Ljubljana, Zagreb, Beograd etc.
Martin Sieghart was born in Vienna, where he received his formative musical education: the violoncello, piano, organ and conducting. After his studies he collected valuable experience as principal cellist of the Vienna Symphony Orchestra, which later proved extremely useful. During this period he was intensely involved in church music. Furthermore, he has performed as a chamber musician with the "Wiener Instrumentalsolisten", the "Eurasia-Quartett" and the "Concentus Musicus" with Nikolaus Harnoncourt.
In 1985 he switched roles from cellist to become assistant conductor of G. Rozhdestvensky. After stepping in as a conductor for the Stuttgart Chamber Orchestra, the oldest chamber orchestra in Germany, they appointed him the successor of their legendary chief conductor Karl Münchinger. In 1992 he was also appointed the Chief Conductor of the Bruckner Orchestra Linz and the Linz Opera House. He has recorded numerous CDs with both orchestras. Under his creative leadership they developed to a distinguished international operating orchestra with numerous recordings, among others, Mozart's "The abduction from the Seraglio" and several Bruckner-symphonies.
Sieghart has an exceptional love for the music of the Strauss family. He directed the Johann Strauss Orchestra during its tour of Japan over four years. He has dedicated concert programmes to these composers with the Vienna Symphony Orchestra, the London Philharmonia and his own orchestra in Arnhem. At the Leipzig Opera house he directed a premiere of "Die Fledermaus".
At the end of his activities in Stuttgart and Linz he expanded his artistic activities and was appointed Professor at the University of Music and Peforming Arts, Graz. In 2003 he became chief conductor of the Arnhem Philharmonic Orchestra and founded his own open air festival, 'Mozart in Reinsberg', dedicated to the operas of Mozart.
There was also the special task of being director of the international chamber orchestra 'Spirit of Europe', which recruited members from over ten nations. In 2012, Sieghart founded the "EntArteOpera" festival together with Susanne Thomasberger and Philipp Harnoncourt. The purpose of this festival was to restore works which had been vilified during the Third Reich as degenerate. The Israel Chamber Orchestra was invited as the festival orchestra which Sieghart was also the principal guest conductor of during those years.
With the Japanese record label "Octavia Records", Martin Sieghart cherishes an intense collaboration, which resulted in the highly respected first recording of the 10th symphony of Gustav Mahler in the version of Mazucca and Samale with the Arnhemer orchestra.
Sieghart works with numerous orchestras: Philharmonia Orchestra London, Wiener Symphoniker, RAI Roma, Japan Philharmonic Orchestra, NDR Sinfonieorchester, Residentie Orkest Den Haag, Radio Symphonieorchester Wien, Slovenian Philharmonic Orchestra, WDR Symphonieorchester, Mozarteum Orchester Salzburg, Tchaikovsky Symphony Orchestra, Deutsches Symphonie-Orchester Berlin, Tokyo Symphony Orchestra, Tonkünstlerorchester Niederösterreich.
The Season 2015/16 is the last at the university. From autumn 2016 onwards Sieghart will return once more entirely to conducting. Numerous concerts in Germany, Japan, South America, Italy and Spain etc. have been confirmed. Also, his first book is in development. It should be understood as a kind of 'Quodlibet' for young conductors. Following Paul Watzlawick, it will be titled "Anleitung zum Unglücklichsein eines Dirigenten". It will deal humorously with the universal problems of conducting and how best to master them.
