Watch Vilém Veverka a Ensemble Opera Diversa (2018) : Full Movie Online Free Renowned Czech oboist in the Janáček Philharmonic Orchestra Ostrava chamber music series. Vilém Veverka, one of the most respected Czech oboists, performs as a soloist with major orchestras and has performed a number of demanding compositions from the second half of the 20th century in European premieres. This time, he will present important works by Czech composers to the audience together with the string orchestra Ensemble Opera Diversa. The highlights of the concert are compositions by Gideon Klein and Pavel Haas, who belong to the so-called Terezín composers. Pavel Haas' Suite for Oboe and Piano, Op. 17, was composed in the autumn of 1939 under the shadow of occupation, and its arrangement for oboe and string orchestra by composer Ondřej Kyas is a reference to the unfinished nature of Haas' composition.
