The recordings of Roberto DÃaz include a critically acclaimed live recording of Jacob DruckmanÂs Viola Concerto with the Philadelphia Orchestra conducted by Wolfgang Sawallisch, and for Naxos works for viola and piano by Henri Vieuxtemps. An active chamber musician, he has performed with artists such as the Emerson String Quartet, Emanuel Ax, Yefim Bronfman, Christoph Eschenbach, Yo-Yo Ma, Wolfgang Sawallisch, and Isaac Stern.
