While Jaap van Zweden has things handled over at the big-market symphony, taking our musicians around the world to garner international acclaim, there was still a gap in the more experimental small-orchestra sector. Enter scene: Dallas Chamber Symphony. Conductor Richard McKay led the group through its inaugural 2012-13 season at the Dallas Performance Hall, and we sat thrilled, listening as they blended both new and old. There was a youthfulness brought to these offerings, merging more standard, popular works like Beethoven's Symphony No. 7, Mozart's "Overture to the Marriage of Figaro" and selections by Schumann and Brahms with live scores to two silent films and solo piano performances. This type of creative energy is what Dallas needs if it wants to court a new generation of classical music fans. And by the look of DCS's upcoming season, which has not one but two nods to Buster Keaton in the lineup, Dallas Chamber Symphony is just the right group to do it.
