In several concerts this season the BSO celebrates the centennial of the great Leonard Bernstein, the legendary conductor, Broadway and concert composer, pianist, educator, and personality whose talent changed the course of American music. Born in Lawrence, MA, in 1918, Bernstein attended Boston Latin School and Harvard University. A member of the very first class of the Tanglewood Music Center in 1940 and a protégé of legendary BSO conductor Serge Koussevitzky, Bernstein remained a dynamic, irrepressible, and inspiring presence at Tanglewood for fifty years. Led by Andris Nelsons, this Opening Night program features popular vocal selections sung by host Frederica von Stade and acclaimed soprano Julia Bullock, as well as BSO principal flute Elizabeth Rowe. Bookending the program are the composer's delightfully varied Divertimento and familiar, vibrant music drawn from West Side Story.(Some emphasis added.)
The actual listing of the program will enable you to make sense of the last two sentences I quoted from the page.
"West Side Story" is overly familiar, but I'm looking forward to the instrumental pieces at the beginning.
Again, remember this is Friday, beginning at 5:30, Boston Time. The Saturday concert will be at the usual time.
