The wonderful Sphinx Virtuosi, a string orchestra drawn from the nation’s finest Black and Latinx orchestral performers, returns to the Gardner Museum, their Boston home. We are especially excited to hear works by Derrick Skye and Juantio Becenti, both of whom the Gardner has previously commissioned. Sphinx is also bringing music of the remarkable 19th-century composer Teresa Carreño, who was also a globe-trotting pianist. Her music is only now coming to wider audiences. The program also includes a premiere by the wonderful New York-based violinist and composer Curtis Stewart.
