The Czech Philharmonic Low Brass Ensemble, founded in 2004, consists of first-class players from the trombone and tuba sections of the foremost Czech orchestra. The delectable, velvety sound and specific expressivity of these instruments playing together is completely different from what we hear in a brass quintet or a traditional trombone quartet, and for this reason ensembles of this type are not uncommon throughout the world. During the thirteen years of its existence this one has given numerous successful concerts, appearing repeatedly in the Czech Philharmonic Chamber Series and concerts of the Czech Society for Chamber Music as well as for example in the Lipa Musica Festival and the St. Wenceslas Festival. The repertoire includes arrangements of pieces from various style periods but also works written by contemporary composers directly for this group. In 2014 the ensemble issued a profile compact disc presenting a representative cross section of its repertoire.

The ensemble’s artistic director, trombonist Robert Kozánek, is a graduate of the Pavel Josef Vejvanovský Conservatoire in Kroměříž and the Academy of Performing Arts in Prague. He has won honours in numerous international competitions, for instance in Geneva, Gdańsk, Markneukirchen, Jeju (Korea), and Lieksa (Finland). He is a sought-after player not only as a soloist (appearing with the Bohuslav Martinů Philharmonic of Zlín, the Plzeň Philharmonic, and the Prague Philharmonia) but in chamber music and not least as a jazzman. Since 2002 he has been principal trombonist of the Czech Philharmonic, and since 2003 he has been teaching at the Janáček Academy of Performing Arts in Brno.
