In 1970 he founded Quanta, a collective improvisation group. He also worked at the electronic music studios of Tokyo radio and television in 1972. At the end of the 1970s and beginning of the 1980s he closely collaborated with renowned performers in solo and chamber works where he explored unusual timbre possibilities by the use of extended techniques. In 1982, he founded Pauta, one of the most important music journals in Latin America, and continued to serve as its chief editor. In 1987, he received a Guggenheim Fellowship for his first (and only) opera Aura, based on the short story by Carlos Fuentes. Aura premiered in 1988 at the Palacio de Bellas Artes in Mexico City.[1]
Lavista approached religious genres in a series of compositions where he used Medieval and Renaissance procedures, such as the symbolic use of certain intervals, canonic permutations, and isorhythm, most evident in the Missa ad Consolationis Dominam Nostram, a central work in his oeuvre.[citation needed]
He received multiple awards and honors: Premio Nacional de Ciencias y Artes and the Medalla Mozart in 1991, an honorable mention from the Sistema Nacional de Creadores del Fondo Nacional para la Cultura y las Artes in 1993, and membership in the prestigious El Colegio Nacional since 1998. Lavista’s works are frequently performed in Europe and throughout the Americas, where he travelled regularly to give lectures and seminars in composition. Since 1970 he taught music analysis and composition at the National Conservatory in Mexico City. Additionally, he was visiting professor at the University of Chicago, Cornell University, the University of California San Diego, Indiana University, McGill University, University of North Texas, and The University of New Mexico.
