Translated from Russian:

Several times I had an opportunity to visit Physical Therapy studio at Carnegie Hall in New York City, one of the most prestigious concert halls in the United States.
Mr. Shmuel Tatz has the most extensive knowledge of physical therapy. Personally for me, he helped to relieve muscle tension as a result of my many concerts and rehearsals.
Mr. Tatz has not only a great repertoire to affect the muscles of professional performers, but also a unique talent of psychological impact to the patient.
My colleagues - famous musicians Yehudi Menuchin, Isaak Stern and many others - were very grateful to Mr. Tatz for his help in continuation of their long careers of successful performers.
I read his printed works with great admiration and I think they are worth the highest praise.
