The Master Singers of Lexington is an outstanding 30-voice chamber chorus that performs a wide range of secular and sacred chamber choral literature from the 16th century to the present. Under the leadership of Adam Grossman, the group performs staples of the choral repertoire by composers such as Bach, Schumann, Mozart and Mendelssohn, and also enlivens concerts with innovative programming featuring less familiar works and new music, especially from local composers. The Master Singers serves the general public of greater Boston, with a special focus on Lexington and the western suburbs.
