In 2005, he became Director of the Wrocław Philharmonic and the International Festival Wratislavia Cantans and effected structural and profile transformation of both institutions, finally merging them into the National Forum of Music. The opening of the new venue of the NFM – which was constructed thanks to his ideas and efforts – was honoured with the Coryphaeus of Polish Music 2016 award in the Event of the Year category. 

As Director of the NFM, he created new artistic ensembles, i.a. the NFM Choir, Wrocław Baroque Orchestra and the NFM Boys’ Choir.

Music of the past is of particular interest to Andrzej Kosendiak. In 1985, he founded the ensemble Collegio di Musica Sacra, and in 2012 Wrocław Baroque Ensemble, of which he is Artistic Director. He has recorded previously unknown works from Wrocław University Library and Strasbourg Library, works of Grzegorz Gerwazy Gorczycki (awarded Wrocław Music Prize), Bartłomiej Pękiel, Stanisław Sylwester Szarzyński, Jacek Różycki, and others; most of these recordings were nominated for Fryderyk awards: Mielczewski II won a Fryderyk 2019 (Album of the Year – Early Music), and Mikołaj Zieleński triumphed in the same category, winning a Fryderyk in 2021. The CD with works by Zieleński was also nominated for International Classical Music Awards 2021 in the Baroque Vocal category. In 2022, new recordings directed by him were released: a vinyl disc with Gorczycki’s Completorium and  the CD Marcin Józef Żebrowski – Vesperae in Visitatione Beatae Mariae Virginis (awarded Fryderyk 2023 and nominated for Opus Klassik 2023 in the categories: Conductor of the Year and Ensemble of the Year). In 2023, the album recorded with Marcin Szelest – Musica liturgica – was published, featuring all the preserved works by Marcin Leopolita and other works for organ.
