Extremely sensitive to the color (timbre) of their own sound, the Ysaye Quartet performs with flair and great attention to musical nuance. The ensemble, which has been together for almost 30 years, brought all their gifts to a monumental work in the string quartet literature in a Schubert Club/Music in the Park Series concert. The Ysaye Quartet's performance of the Brahms String Quartet Op 51, No. 2 flows like liquid gold. That concert from just last month is this week's Regional Spotlight.
