Curious about Itzhak Perlman’s recovery from shoulder surgery in February, I did a little searching around. He is back to a “normal” touring schedule, however he has been substituting less strenous pieces. In Baton Rouge he replaced the Tchaikovsky violin concerto with Beethoven. He helped close the Tanglewood season with Mozart’s Third Concerto, in lieue of the originally planned Bruch concerto. With his full schedule, he is likely avoiding overworking the shoulder and recovering at a suitable pace.
