BORROMEO STRING QUARTET Even older than Tanglewood, the venerable South Mountain Concerts offer a wealth of chamber music options in the Berkshires after the Boston Symphony Orchestra summer season has ended. This year’s lineup includes an appearance by the Borromeo Quartet performing works by Beethoven and Dvorak alongside the premiere of a new quartet by Lera Auerbach. Sept. 8, 3 p.m., Pittsfield. 413-442-2106, www.southmountainconcerts.org
A FAR CRY The well-traveled conductorless chamber orchestra opens its new season with a Bohemian-themed program of works by Gideon Klein, Josef Suk, and Mozart (the “Prague” Symphony, naturally). Sept. 7, 8 p.m., Jordan Hall. 617-585-1260, www.necmusic.edu
