You've likely seen many virtuoso pianists and perhaps a even a few brilliant dueling acts. But how many piano-playing trios have you witnessed? See one of these rare and unique groups on stage when Trio PhilaGrande presents Six Hands - One Soul at Philadelphia's Glen Foerd on the Delaware. As part of the Mosaica Musica in the Mansion series, Tatyana Mykhailova and Dmitry and Olga Borisovsky, will perform renowned pieces by Mozart, Saint Saens and Ravel, as well as beautiful music by lesser-known composers W.F.E. Bach, Gurlitt and Streabbog, written specifically for piano trio.
