Lauded by the Philadelphia Enquirer for his "electric presence" and by the American Record Guide for his "rich, deep, mellifluous tone, impeccable intonation," and "excellent sense of timing and tempo," viola master Roberto Díaz acts as featured guest in the Quad City Symphony Orchestra's fifth Masterworks presentations of the ensemble's 2024-25 season, the gifted musician lending his talents to the March 1 and 2 performances of Echoes of Exploration.
