Hōkūleʻa, as every Hawaiian schoolchild can tell you, is a 62-foot replica of a traditional Polynesian double-hulled voyaging canoe, launched in 1975 by the Polynesian Voyaging Society. Its purpose: to revive ancient practices of navigation by the stars, winds, and currents. Over the past half century, the vessel has logged more than 140,000 nautical miles, establishing new ties of friendship wherever it goes. Michael-Thomas Foumai’s choral symphony Raise Hawaiki, receiving its first full performance, celebrates the 50th anniversary of the craft’s maiden voyage to Tahiti. Historic and current imagery complements Foumai’s splashy cinematic score. As a curtain raiser, there’s Britten’s Four Sea Interludes from Peter Grimes. Anthony Parnther conducts. —Matthew Gurewitsch
