The South Coast Chamber Music Series presents “Trio Trio” on Saturday, Nov. 30 in Marion and Sunday, Dec. 1 in South Dartmouth.

The concerts’ musicians are Nicholas Brown (clarinet), Jesse Holstein (violin), Leo Eguchi (cello) and Janice Weber (piano).

“Three powerful trios prove that less can be so much more,” an announcement said.

The New Bedford Symphony Orchestra, a professional orchestra, annually presents a concert series of classical and pops music with internationally acclaimed guest artists, as well as a chamber music series.

New Bedford Symphony Orchestra clarinetist Nicholas Brown “lends his artistry to Aram Khachaturian’s incisive Trio of 1932 and Brahms’s late, sublime Clarinet Trio, Op. 114,” the announcement said.

“The 1987 Piano Trio by Ellen Taaffe Zwilich, much praised for its clarity, wit, and semblance to a bolt of lightning, reinforces her reputation as one of the finest composers of her generation,” the announcement said.

Concerts have a new start time this season. Saturday concerts in Marion begin at 3 p.m. at St. Gabriel’s Episcopal Church, 124 Front St. Sunday concerts in South Dartmouth begin at 3 p.m. at St. Peter’s Episcopal Church, 351 Elm St.
