The Boston Symphony Orchestra opens its 2011 summer season at Tanglewood with an all-Italian program, under the direction of Charles Dutoit, on Friday, July 8, at 8:30 p.m. in the Koussevitzky Shed. The BSO and Dutoit will be joined by the acclaimed Tanglewood Festival Chorus and a cast of distinguished soloists for excerpts from Act 1 of Bellini’s Norma and the Trio from Act 3 of Verdi’s rarely performed I Lombardi. The evening will feature the BSO debuts of soprano Angela Meade, Italian tenor Roberto De Biasio, and up-and-coming tenor Matthew DiBattista, who will be joined by the acclaimed American mezzo-soprano Kristine Jepson, and the critically celebrated American bass-baritone James Morris. Two orchestral favorites—Rossini’s William Tell Overture (popularized as “The Lone Ranger” theme) and Respighi’s evocative tone poem Pines of Rome, closing the concert, will spotlight the orchestra in this opening concert of its summer season, June 25-September 4.
