On July 20, musicians of the Philadelphia Orchestra will perform with members of Canada’s National Arts Centre Orchestra at Ambassador David L. Cohen’s residence in Ottawa in an event that promotes trade and learning between Philadelphia and Canada. The visit will include string quartet performances plus master classes, sectionals, and side-by-side performances with student musicians of the Ottawa Youth Orchestra Academy and a free performance on July 20 for Ukrainian refugees at Café Ukraine, a drop-in center where refugees can meet, share coffee and stories, and seek resources to adjust to life in Canada. A string quartet of Philadelphia Orchestra musicians will perform music by Dvořák and Florence Price; a quartet from the National Arts Centre Orchestra will perform music by Canadian composer Carmen Braden. Quartets from both orchestras will perform the first movement of Mendelssohn’s String Octet. The events are part of the Greater Philadelphia Trade Visit to Canada, an initiative to develop trade opportunities and business relationships between Canadian and Philadelphian minority-owned small and medium-sized enterprises. The musical activities follow a July 19 convening to develop trade opportunities and business relationships.
