Karol Mossakowski, * 1990, is highly regarded as a performer and improviser. His extensive musical education began at the age of three, when he received piano and later organ lessons from his father. After studying music in Poland, he entered the organ, improvisation and composition classes at the Paris Conservatoire (CNSMDP), where he enjoyed lessons with Olivier Latry, Michel Bouvard, Thierry Escaich and Philippe Lefebvre.
Among Mossakowski's many awards are a first prize at the Prague Spring International Competition in 2013 and the Grand Prix de Chartres in 2016. In 2014/2015 Karol spent six months as Young Artist in Residence at Saint-Louis Cathedral in New Orleans, where he gave numerous concerts and masterclasses in interpretation and improvisation. Mossakowski's special concern is to express himself musically through improvisation, which he likes to give a special place in his concert programmes or in the accompaniment of silent films. He has played cinema concerts at the Festival de Cinéma in Québec or at the Festival Lumière in Lyon, where he accompanied Dreyer's film "Jeanne d'Arc" in the Auditorium de Lyon, a production recently released on DVD by Gaumont.
As a soloist, he has performed at Radio France, the Paris Philharmonic, the Warsaw and Moscow Philharmonic, the Marinsky Theatre in St. Petersburg, the Bamberg and Dresden Philharmonics, and the cathedrals of Berlin, Cologne, Vienna and Milan, among others.
As a soloist with orchestra he has performed with the Orchestre National de France, the Warsaw Symphony Orchestra and the Odense Symphony Orchestra under conductors such as Myung-Whun Chung, Kent Nagano, Mikko Franck and Lawrence Foster.
Karol Mossakowski teaches improvisation at the Basque Country Conservatory in San Sebastián and is titular organist at Lille Cathedral.
He is currently artist in residence with the Polish National Radio Symphony Orchestra, having held the same position with Radio France between 2019 and 2022.
In November 2021, Tempéraments released his first album " Rivages ", recorded on the Grenzing organ at the Radio France auditorium. Here he plays works by Bach, Mozart, Mendelssohn and Liszt, combining them with improvisations.
As composer in residence at the Festival de musique sacrée of Saint-Malo, he composed " Les Voiles de la lumière ", an oratorio for mixed choir and three organs, first performed in 2021, and " Trois Versets " for three organs, first performed in 2022.
