For the first time in vinyl format the work of the Bolivian avant-garde composer, Cergio Prudencio, together with the Orquesta Experimental de Instrumentos Nativos (OEIN). The OEIN is the result of the incorporation of Aymara musical traditions into the realm of contemporary music to produce a new sonic world. The work of Bolivian composer Cergio Prudencio (La Paz, 1955) is indissolubly linked to the project of the Orquesta Experimental de Instrumentos Nativos Experimental Orchestra of Native Instruments (OEIN), which he co-founded in 1980 and of which he is the emeritus director. It constitutes one of the most challenging adventures in the music that has emerged in Bolivia and Latin America. The OEIN is the result of the incorporation of Aymara musical traditions into the realm of contemporary music to produce a new sonic world. In the composer's words, it is about "...finding in the indigenous conception of music, elements of change and transformation, to establish a historical continuity." This incorporation is not only based on using native instruments but also involves integrating their socio-historical context and philosophies from the Andean indigenous world. In addition to forming ensembles with highland native instruments (sikus, tarkas, mohoceños, pinkillos, wankaras, seeds, drums, etc.), the foundation is laid on the three structural principles that govern Aymara music: "arca-ira," which means alternation of sounds between two musicians; "tropa," which involves the formation of large ensembles of instrumentalists and sound amplification; and "wakiña," meaning community strength. According to Prudencio, the acoustic and expressive identity of Andean-highland sounds originates from these principles, as does that of the OEIN. The release of Cergio Prudencio - Antología 1: Obras para la Orquesta Experimental de Instrumentos Nativos Cergio Prudencio - Anthology 1: Works for the Experimental Orchestra of Native Instruments allows us to delve into this wealth of thought and sounds, into the work of a fundamental and radical artist, for whom decolonization is also an opening to experimentation and the new. These compositions project a historical memory into the present, constructing new horizons.
