(Photo courtesy DaPonte String Quartet) Part 5 of DaPont String Quartet’s “Onstage” six–part concert series premieres May 15 with Stravinsky, Three Pieces for String Quartet. The concert can be viewed at onstage.daponte.org. Filmed at the Rockport Opera House in April 2021, the May 15 concert release is a work composed in 1914 by Russian-born Igor Stravinsky. Often described as a series of pieces to be played by four strings, rather than a traditional String Quartet, this work challenges the notion of a classically structured chamber music string quartet, according to DaPonte, in a news release.
