Bookended by two of Florence Price’s fantasies for violin and piano, this recital contrasts the exotic with the mainstream. Price wrote once that “In all types of Negro music, rhythm is of preeminent importance.” Against the fiery drive of the Price pieces and Bartok’s Second Sonata, based on Eurasian folk music, violinist Ann Yu and pianist Irwin Shung pit the more familiar yearning featured in Brahms’ and Bach’s compositions for string and keyboard.
