Biography
Biography
Díaz's primary teachers were his father Manuel Díaz, Burton Fine, Louis Krasner, and Joseph de Pasquale. His recording of transcriptions by William Primrose with pianist Robert Koenig was nominated for a 2006 Grammy Award. Díaz has recorded an album of the viola music of Vieuxtemps with Robert Koenig, and the Brahms Sonatas with American pianist Jeremy Denk. Díaz was born in Chile, and grew up in Atlanta, Georgia. He currently plays on a 1600 Antonio & Girolamo Amati viola once owned by William Primrose, having previously owned a 1743 Carlo Landolfi and a Camillus Camilli from 1739.
