He again performed with that orchestra two years later as soloist in the third piano concerto of Béla Bartók. He also performed with the Dallas Symphony, the St. Louis Symphony, and the Buffalo Philharmonic and gave solo recitals at Alice Tully Hall, Coolidge Auditorium at the US Library of Congress, and various other halls in the United States and Europe.
