Tanglewood, the western Massachusetts summer home of the Boston Symphony Orchestra, celebrates its 50th birthday this weekend with a trio of concerts. Founded in 1937 by then-BSO music director Serge Koussevitzky, Tanglewood’s 210 acres was given to the orchestra by Boston socialite Gorham Brooks. In addition to serving as home for the Berkshire Music Festival, the orchestra’s summer venue, Tanglewood is also an internationally renowned music camp and institute, numbering Leonard Bernstein, Seiji Ozawa and Lorin Maazel among its former students. The gala weekend includes performances by flutist James Galway, soprano Leontyne Price--and lots of fireworks.
