After her studies in music pedagogy in Munich, Heidi Gröger, an Eichstätt native, studied Baroque violoncello with Jaap ter Linden and Viola da gamba with Philippe Pierlot at the Royal Conservatory in The Hague. In 2007 she received her Master’s degree with distinction there. Scholarships such as the Huygens Foundation and First Prizes at the International Early Music Competitions in York (GB), Wassenaer (NL) and Neuburg an der Donau followed.
Her musical development was already influenced during her studies by participation in ensembles such as the Freiburg Baroque Orchestra, Concerto Vocale, the Berlin Baroque Soloists and Harmonie Universelle. With her own Ensemble Fleury she has recorded the Pièces de clavecin en concerts of J. P. Rameau for Sony Classics for the very first time on a golden viola da gamba with eight strings. For the Bavarian Radio she has recorded Diletto Musicale for viola da gamba solo by G. Thim (*1922).
In collaboration with Johannes Weiss, she has organized numerous concerts and the newly initiated Summer Courses at Castle Seehaus (Middle Franconia). Since 2011 Heidi Gröger teaches viola da gamba at the University of Music in Frankfurt am Main.
Johannes Weiss is a singer, conductor, and harpsichordist, primarily dedicated to the music of the 17th and 18th centuries. In addition to maintaining international concert and opera engagements, he regularly works as a tenor soloist with Akadêmia France and teaches historical performance practice and singing at the Early Music Summer School in Valtice. Before turning more to solo singing, Johannes initially studied harpsichord and viola da gamba. On both instruments he won several competitions, including the Biagio Marini Competition, the Van Wassenaer Concours and the Early Music Competition of the Foundation Preußischer Kulturbesitz in Berlin.
Singing came more and more into focus at the same time, and Johannes received inspiration through his studies with Hedwig Fassbender, in masterclasses with Christoph Prégardien, Ernst Häfliger, Guillemette Laurens and Thomas Heyer, and as a member of the Atelier Lyrique of the Paris Opera. He has sung solo roles at the Oper Frankfurt, the Freie Landestheater Bayern, the Hessische Staatstheater Wiesbaden, the Opéra La Monnaie in Brussels, the National Theater in Prague, the Opéra National de Paris, the Danzig Opera, the Opéra de Monte Carlo, and the Kammeroper Schloss Rheinsberg.
Through his work as artistic director, teacher, and conductor, Johannes Weiss goes beyond simply making music – he endeavors to form and to mold the current musical landscape, driven by the goal of inspiring more people to feel passionate about music.
