Georg Grün can count himself among the internationally demanded choral conductors and choral sound specialists. He founded the KammerChor Saarbrücken in 1990 and is still its artistic director. From 2000 to 2013, Georg Grün held a professorship for choral conducting at the Musikhochschule Mannheim, with whose newly founded chamber choir he also won numerous international prizes. In 2012 he followed a second call and moved to the Hochschule für Musik Saar as professor, at the same time taking over the direction of the BachChor Saarbrücken.
Georg Grün travels the world as a guest conductor, guest professor, adjudicator and lecturer of international master classes for choral conducting. He has been a mentor of the Conductors' Forum at the German Music Council since 2010 and was jury chairman of the renowned Marktoberdorf International Chamber Choir Competition from 2015-2019. He is increasingly involved in improvisation (piano/organ) and performance and is also active as a composer and arranger. Concerts, jury activities, master classes and guest conductorships have taken him to Japan, Taipei and the USA in the 2019-20 season.
