Conductors had mixed responses to Gould and his playing habits. George Szell, who led Gould in 1957 with the Cleveland Orchestra, remarked to his assistant, "That nut's a genius." Leonard Bernstein said, "There is nobody quite like him, and I just love playing with him." Bernstein created a stir at the concert of April 6, 1962 when, just before the New York Philharmonic was to perform the Brahms Piano Concerto No. 1 in D minor with Gould as soloist, he informed the audience that he was assuming no responsibility for what they were about to hear. He asked the audience: "In a concerto, who is the bossthe soloist or the conductor?", to which the audience laughed. "The answer is, of course, sometimes the one and sometimes the other, depending on the people involved." Specifically, Bernstein was referring to their rehearsals, with Gould's insistence that the entire first movement be played at half the indicated tempo. The speech was interpreted by Harold C. Schonberg, music critic for "The New York Times", as an abdication of responsibility and an attack on Gould. Plans for a studio recording of the performance came to nothing. The live radio broadcast was subsequently released on CD, Bernstein's disclaimer included.
