What’s the link between the Finnish composer Kaija Saariaho, who died in June, and the early-20th-century titans Erich Wolfgang Korngold and Darius Milhaud? A mutual flair for the theatrical, which is reflected in the title of Parlando’s concert on Sunday: “Melodrama.”

While all three artists wrote operas, this chamber orchestra will focus on some smaller yet substantial works: Milhaud’s “Le Bœuf sur le toit,” Saariaho’s “Graal théâtre” (featuring the violinist Geneva Lewis), and Korngold’s “Much Ado About Nothing” Suite. By giving short spoken introductions to each piece from the stage, the orchestra’s conductor and founder, Ian Niederhoffer, makes good on its motto: “Every concert tells a story.” But smart, unusual programming on this level fosters a gripping narrative of its own, too.
