Please answer the following question: What is the answer for the question: Who was described as being very tense at rehearsals? from the following article ?

It was the first time in its 80-year history that the orchestra had played outside of North America. The orchestra received plaudits from European critics, and was welcomed home at the end of the tour with a ticker-tape parade.The orchestra's principal flute player, Donald Peck, commented that the relationship between a conductor and an orchestra is difficult to explain: "some conductors get along with some orchestras and not others. We had a good match with Solti and he with us." Peck's colleague, the violinist Victor Aitay said, "Usually conductors are relaxed at rehearsals and tense at the concerts. Solti is the reverse. He is very tense at rehearsals, which makes us concentrate, but relaxed during the performance, which is a great asset to the...
