Conrado Silva was born in Montevideo, Uruguay, in 1940. There, he studied engineering with a specialisation in acoustics, and composition with Hector Tosar. In 1969, he took up residence in Brazil and started his career as an educator by teaching acoustics and electroacoustic music composition at the Department of Music at the University of Brasilia. During the 1960s, he attended several courses on composition and workshops worldwide with Stockhausen, Kagel, Ligeti, Pousseur and John Cage.

Conrado is an important figure in Latin America both as a composer and educator. He is one of the pioneers of computer music in Brazil and Uruguay, and, for fifteen years, one of the creators and directors of the Cursos Latino-Americano de Musica Contemporanea (Summer courses on Contemporary Music) held each year in different countries in Latin America. Conrado's works have been performed and broadcast worldwide. His opera Espacos Habitados ( Inhabited Spaces), for female voice, actor and live digital equipment was staged in 1994.

He is a founder member and General Secretary of the board of directors of the Sociedade Brasileira de Musica Electroacustica (Electroacoustic Music Society of Brazil) and member of NUCOM (Brazilian Computer Music Society).
