Guido Mancusi was a soprano soloist with the Vienna Boys' Choir. He graduated from the Vienna Music High School and then studied at the Vienna Conservatory (bassoon and singing) and at the Vienna University of Music (composition with Erich Urbanner and conducting with Karl Österreicher), graduating with honours. Mancusi is the founder of the Baroque Ensemble Vindobona. He was musical assistant to Adam Fischer and Riccardo Muti at La Scala in Milan and at the Bayreuth Festival. Since 1998, Mancusi has been principal conductor of the Schönbrunn Palace Orchestra Vienna, which specialises in Viennese classical music. As a conductor, he has performed at the Vienna Festival, the Vienna Klangbogen, and in England, Argentina, Japan and the USA. Mancusi is currently a professor at the Vienna Conservatory Private University and works as a freelance concert conductor.
Guido Mancusi's work as choir director with Chorus Viennensis began with a great success: winning first prize and the interpretation prize at the 5th International Franz Schubert Male Choir Competition. Mancusi has created many compositions and arrangements (including Viennese songs) for male choir and has greatly expanded the repertoire of the Chorus Viennensis (Schubert, Hindemith, Schönberg, etc.). Challenging concerts and significant CD productions (with Philips and ORF) have raised the choir to a professional level under his direction.
