Since 2007, Lukáš Vasilek has been the principal conductor of the Prague Philharmonic Choir, with his work entailing exploration and performance of the a cappella repertoire, as well as the ensemble’s preparation for signing in great cantata, oratorio and opera projects. As a conductor or choirmaster, he has participated in numerous recordings the Prague Philharmonic Choir has made for prestigious labels, including Decca and Supraphon. Lukáš Vasilek has guided the Prague Philharmonic Choir in the majority of their activities in the Czech Republic and abroad, cooperating with world-renowned conductors (Jiří Bělohlávek, Semyon Bychkov, Manfred Honeck, Jakub Hrůša, Philippe Jordan, Fabio Luisi, Tomáš Netopil, Gianandrea Noseda and Simon Rattle) and orchestras (Berlin Philharmonic, Czech Philharmonic, Israel Philharmonic, St. Petersburg Philharmonic, Vienna Symphony). Since 2010 the choir has been the ensemble in residence of the Bregenz Festival. Besides leading the Prague Philharmonic Choir, Lukáš Vasilek has pursued other artistic activities. He has regularly worked with Martinů Voices, a vocal ensemble he himself founded in 2010, primarily focusing on chamber choral music dating from the 19th to 21st centuries, yet also devoting to earlier music. Under Vasilek, Martinů Voices have mainly given independent concerts, yet they have also performed along with other ensembles. Moreover, they have made acclaimed albums, (Bohuslav Martinů’s and Jan Novák’s chamber choral works).
