"He conducts with his whole body - arms, head and behind together. At moments he seems to dance on his knees; he crouches down; he makes tense and pulsating movements, like electric vibrations, with his hands. He gives explanations in very bad French, and sings out of tune passages that he wants played again; he cares nothing for ridicule; he always looks bored, sulky half asleep - but nevertheless lets nothing escape him."
