The Boston Philharmonic Orchestra has revealed that after 48 years the ensemble and its Boston Philharmonic Youth Orchestra will wind down operations next June.

Founded by Benjamin Zander in 1979, the BPO has won plaudits for its performances of the German Romantic canon, particularly the music of Beethoven, Bruckner, and Mahler.

The orchestra has been comprised of freelance professionals, college-aged music students, and skilled avocational musicians.

Performance dates for both groups’ final seasons have yet to be announced, but repertoire will include symphonies by Beethoven and Mahler. The BPO’s final concert will be of the latter’s Symphony No. 9—the same work it presented in its first concert in 1979.

The orchestra next performs Mahler’s Symphony No. 3.
