Wu Man played two solo pieces to open this concert. Delicate and intricate, they brilliantly demonstrated her technique with lyrical melodies, dramatic tremolos and percussive snaps. But this concert, presented by the Aga Khan Music initiative, was titled “Old and New Music from the Ends of the Silk Route” and Wu Man was joined by three Syrian musicians on saxophones, qanun zither and vocals plus Andrea Piccioni on frame drums.
