The Boston Symphony Orchestra (BSO) is an American orchestra based in Boston, Massachusetts. It is one of the five major American symphony orchestras commonly referred to as the “Big Five”. Founded in 1881, the BSO plays most of its concerts at Boston’s Symphony Hall and in the summer performs at Tanglewood.
Andris Nelsons is the current music director of the BSO. Bernard Haitink currently holds the title of conductor emeritus of the BSO, and Seiji Ozawa has the title of BSO music director laureate.
In the wake of Levine’s resignation, Andris Nelsons made his first guest-conducting appearance with the BSO in March 2011, as an emergency substitute for Levine at Carnegie Hall in Mahler’s Symphony No. 9. He subsequently guest-conducted the BSO at Tanglewood in July 2012, and made his first appearance with the BSO at Symphony Hall in January 2013. In May 2013, the BSO named Nelsons as its 15th music director, effective with the 2014-2015 season. His initial contract is for 5 years, with 8–10 weeks of scheduled appearances in the first year of the contract, and 12 weeks in subsequent years. Nelsons held the title of Music Director Designate for the 2013-2014 season. In August 2015, the BSO announced the extension of Nelsons’ contract as music director through the 2021-2022 season, with a new contract of 8 years to replace the initial 5-year contract, and which also contains an evergreen clause for automatic renewal.
