It was in 1986 that he turned firmly back to composing. His Canto LLano 1976, his most often-played work, as well as Secretos 1986, and his music for the Franco-Venezuelan movie Oriana 1985 (prize for best music at the Mérida Festival ‘86), already included elements of “environmental music,” and the feeling of sound manipulated in “real time,” which is the conceptual cornerstone of the 24-hour macroformat conceived for the music at Casa Bonita 1988: this composition consists of three great simultaneous works, each lasting eight hours, where the composer has poured in the results of 15 years of research and reflection about sound.
