A violist of international reputation, Roberto Díaz is President and CEO of the Curtis Institute of Music, following in the footsteps of renowned soloist/directors such as Josef Hofmann, Efrem Zimbalist (Daniel Heifetz‘ teacher), and Rudolf Serkin. As a teacher of viola at Curtis and former principal viola of the Philadelphia Orchestra, Mr. Díaz has already had a significant impact on American musical life and continues to do so in his dual roles as performer and educator.
As a soloist, Mr. Díaz collaborates with leading conductors of our time on stages throughout North and South America, Europe, and Asia. He has also worked directly with important 20th- and 21st-century composers, including Krzysztof Penderecki, whose viola concerto he has performed many times with the composer on the podium and whose double concerto he premiered in the United States during the 13-14 season; and Edison Denisov who invited Mr. Díaz to Moscow to work on his viola concerto. Ricardo Lorenz, Roberto Sierra and Jennifer Higdon have all written concerti for Mr. Díaz.
In addition to his decade-long tenure as principal viola of the Philadelphia Orchestra, where he performed the entire standard viola concerto repertoire and gave a number of Philadelphia Orchestra premieres, Mr. Díaz was principal viola of the National Symphony under Mstislav Rostropovich, a member of the Boston Symphony under Seiji Ozawa, and a member of the Minnesota Orchestra under Sir Neville Marriner. Mr. Díaz plays the ex-Primrose Amati viola.
