Airs Monday, July 28 at 11 a.m. This week on the Pittsburgh Symphony pianist Shai Wosner will join maestro Rafael Fruhbeck de Burgos for a performance of Mozart's wonderful Piano Concerto No. 15 and then Mr. Wosner will give us a delightful rendition of Franz Schubert’s Hungarian Melody. The concert will open with Mozart’s Serenade No. 6 in D Major, The "Serenata notturna," and we'll also hear Bela Bartok’s Concerto for Orchestra and from the archives we'll remember Fritz Reiner leading the orchestra in Bela Bartok’s Concerto for Orchestra, (Movement 4).
