So Percussion are, as befits their name, both effusion and simplicity—a clan of Yale grads who push drumming into original, symphonic scope. Unlike other beat-driven clans, though, these erudites are entirely accessible, from the everyday instruments they retextualize (glockenspiel, toy piano, even duct tape) to their newly established So Percussion Summer Institute, an annual chamber music camp for college-age percussionists on the Princeton University campus. Tonight, they perform Imaginary City, a new reflection on urban sounds inspired by Italo Calvino's novel Invisible Cities and commissioned as part of BAM's 2009 Next Wave Festival. It will be a multifaceted marvel.
