The Slavko Osterc Ensemble (1961–1981)Weiss, Jernej (Avtor) Slavko Osterc EnsembleIvo Petrićpremiere performancesabroadpromotionThe 1960s saw the formation throughout Europe of numerous groups specialising in the performance of New Music. Unlike classical ensembles, these groups were able to adapt their instrumental line-ups as required, and were particularly receptive to experimentation of every kind. In Slovenia they included both the Collegium musicum society, founded in 1957 by Pavel Šivic under the aegis of the Composers’ Club, and the Slavko Osterc Ensemble, founded in 1961 by members of the composers’ group Pro musica viva as a vehicle for the performance of their own works. The spiritus agens and conductor of the latter ensemble was Ivo Petrić (1931–2018). Petrić, who headed the DSS’s publishing arm Edicije Društva slovenskih skladateljev from 1970 until 2002, was also the ensemble’s artistic director from the outset. The ensemble’s activities encouraged the creation of numerous new compositions and contributed to the affirmation of Slovene creativity abroad. The ensemble gave almost 170 concerts, made 140 recordings for national and international radio stations and appeared in nearly 40 television broadcasts. It also premiered 65 works by nineteen Slovene composers, with 40 of these premiere performances taking place abroad and 25 in Slovenia. More than 110 performers passed through the ensemble’s ranks during its initial two decades of activity. Petrić was for the most part able to bring together excellent musicians, with whom he achieved concert performances of a high level of quality, as demonstrated by the numerous reviews published in domestic and foreign media. The paper focuses primarily on the ensemble’s performances abroad, while also highlighting certain events that marked the concurrent activities of the Society of Slovene Composers.Založba Univerze na Primorskem in Festival Ljubljana20262026-03-10 12:22:26Delo ni kategorizirano22764ISBN: 9789612935559DOI: https://doi.org/10.26493/978-961-293-555-9.319-331sl
