Concerto for Two Pianos and Orchestra
During his early years, Berkofsky traveled to Europe and twice recorded the long-lost Concerto for Two Pianos and Orchestra of Max Bruch. The first time was with the pianist Nathan Twining and London Symphony Orchestra in 1974. The second recording was with pianist David Hagan and the Berlin Symphony Orchestra in 1978. In addition to his research on this Bruch concerto, Berkofsky also did similar restoration of a duo piano concerto composed jointly by Felix Mendelssohn and Ignaz Moscheles. He also discovered in Paris, and subsequently edited and published, a previously unknown manuscript by Franz Liszt.
