On some aesthetic aspects of the performance of Russian vocal music of the Avantgarde II

20th century, considered in a wide aesthetic context. On the example of the vocal cycles of the 1960s by composers A. Volkonsky, E. Denisov, S. Gubaidulina, A. Schnittke, as well as premier vocal and conductor interpretations, the aesthetic and artistic principles of the domestic musical Avant-garde of the second wave are analyzed. The refusal of avant-garde composers from the traditional musical language, the creation by them of individual musical and technological projects, correspond to a new artistic-aesthetic and sound paradigm. Considering the interpretations of the outstanding singers and conductors of our time - Z. Dolukhanova, L. Davydova, S. Yakovenko, G. Rozhdestvensky, I. Blazhkov, the author draws attention to the features that represent the principles of avant-garde performance: the prevalence of the conceptual-intellectual principle over emotional, refined clarity and refinement of style, honed vocal and ensemble vocal-instrumental technique of music making. Such inalienable properties of artistic and aesthetic appearance of performers-innovators are revealed, such as high general culture, impeccable professionalism, breadth of horizons, aspiration for enlightenment.
