Works for double, triple, and even quadruple choirs, spaced around the audience to provide a uniquely surround-sound experience, are the focus of this concert. From St. Mark’s Cathedral in Venice (which specialized in this chori spezzati) to modern British and American composers, and everything in between. This St Martin’s Chamber Choir concert will be performed in two very resonant spaces – St. Paul Lutheran Church and St. Andrew United Methodist Church in Highlands Ranch.
