This is the first in a three part series outlining the upcoming season for The Boston Cecilia. The next two articles will focus on the December and April concerts, but we begin our 141st season with a spectacular program of Handel and Mozart in Jordan Hall at The New England Conservatory in Boston. The two works to be performed are Handel’s youthful and exuberant setting of Psalm 110, Dixit Dominus, and Mozart’s oratorio that draws on the Psalms of David…and substantial quantities of music from his Great Mass in C Minor…entitled Davide Penitente.
