First compilation brings together the Peruvian experimental scene from 1975 to 1989, a period was the most prolific for a generation of Peruvian artists who, based on musical conceptions derived from modern jazz and techniques inherited from avant-garde music, sought to integrate the sounds of Andean, Afro-Peruvian and Amazonian cultures in search of a new musical universe. Native instruments and folk melodies were used in compositions that demanded modern recording techniques and electronic sounds. This generation was articulated in Lima and was made up of musicians such as Omar Aramayo, Manongo Mujica, Arturo Ruiz del Pozo, Miguel Flores (Ave Acústica), Douglas Tarnawiecki (Espíritus), Luis David Aguilar, Chocolate Algendones and Corina Bartra. But more than a movement, it was a set of individuals from dissimilar origins, who came from rock, jazz, contemporary classical and popular music, but also from the visual arts and poetry, and who had in common the cultural climate of the late seventies and early eighties in a country marked by a series of social and economic transformations, as well as the emergence of new visions and insertions of Andean culture and folklore in the city. The appearance of a mythical substrate connected the work of these musicians and defined an aesthetic, based on the deconstruction of folklore and the exploration of the possibilities that indigenous instruments offered. And from there they could go towards abstract, symbolic and conceptual forms, but also towards more melodic forms, with a strong influence of jazz, while also taking advantage of electronics and the possibilities of the recording studio. Territorio del eco: experimentalismos y visiones de lo ancestral en el Perú (1975-1989) - The Land of Echo: Experimentalisms and Visions of the Ancestral in Peru (1975-1989) - is a compilation that offers an overview of what was one of the moments of greatest creative intensity for experimental music in Peru in its encounter with indigenous sounds. Rescued from private archives and limited editions on cassette, these pieces are reissued for the first time in vinyl LP format. The album includes extensive notes written by Luis Alvarado, author of the compilation, as well as much visual documentation. Cover art by Paloma Pizarro.
