After 1965, he taught music theory at Departamento de Música at the Universidad Provincial "Domingo Faustino Sarmiento" in San Juan, and conducted the choir Agrupación Coral Sanjuanina between 1967 and 1969.

He was invited to compose the music for the large, annual Fiesta Nacional de la Vendimia (Grape Harvest Festival) in 1968.

Later on he transitioned to a more contemporary style, first through the use of twelve-tone techniques and later, during his student years at the Peabody Institute, with elements of experimentalism and the American musical avant-garde trends of the time.

[1] The tango felt very natural to González; it provided opportunities to develop his interest for minor keys, counterpoint, melodic bass lines, harmonic tension and drama.

All printed scores and manuscripts of his works, as well as personal correspondence, were donated to the Special Collections of the American Music Research Center at the University of Colorado Boulder in 2016.

Critic Phillip Scott described González's music "genuine" in a review of the CD Las Puertas del Tiempo in the magazine Fanfare.
