Boston Symphony and Andris Nelsons to Celebrate Tanglewood Center’s 75th Anniversary

There will be nothing understated this summer when the Boston Symphony Orchestra celebrates the 75th anniversary of its summer music academy, the Tanglewood Music Center: Andris Nelsons will conduct the center’s orchestra in a performance of Mahler’s “Symphony of a Thousand,” featuring three choruses and a roster of star soloists including Christine Goerke, Klaus Florian Vogt and Matthias Goerne. Those who cannot make it to the Berkshires for the concert, scheduled for Aug. 8, can watch it on a free live webcast.

The concert promises to be one of the showpieces of the 2015 Tanglewood season, which was announced Thursday. It will be Mr. Nelsons’s first season there since officially becoming music director of the Boston Symphony, and he plans to lead five other programs there in August, featuring music of Beethoven, Shostakovich, Mendelssohn and Strauss. The soprano Kristine Opolais, who is married to Mr. Nelsons, will join him Aug. 15 to perform the Willow Song and “Ave Maria” from Verdi’s “Otello,” among other things.

The season will also feature Neville Marriner conducting Schumann and Mozart; Christoph von Dohnanyi leading an all-Beethoven concert and an all-Mozart concert; and Charles Dutoit conducting Ravel’s “Mother Goose Suite” and Stravinsky’s “Petrushka” on a program with Sibelius’s Violin Concerto, featuring the soloist Leonidas Kavakos. Mr. Goerne will sing Schubert’s “Winterreise,” which he had a big success with this week in New York, and Bryn Terfel and Sondra Radvanovsky will appear in a concert performance of Act I from Puccini’s “Tosca.”

There will also be performances by the Boston Pops, and by pop stars including Tony Bennett and Lady Gaga. The festival will run from June 20 through Labor Day weekend.
