Besprechung des Konzerts vom 30./31.10.1914 (mit der 4. Symphonie) im Philadelphia Inquirer: "[...] With this symphony, Mr. Stokowski and his band struggled. The horn tone was often raw and brassy." und über den Solisten "Mr. Gittelson is something of a problem. He was nervous and lacking in grace, making up for spiritual fire by excessive movements of the body. There was something lacking, something far more elemental than technique, which is the free exercise of genius."
