The movements are: In 1911, Bruch had heard the American duo-pianist sisters Rose and Ottilie Sutro play his Fantasy in D minor for 2 pianos, Op.
Without Bruch's permission, however, they rewrote the concerto themselves to suit their pianistic abilities, copyrighting their version and depositing it with the Library of Congress in 1916.
[7] In 1917 they played a further revised version of the work, with the number of movements reduced from four to three, with the New York Philharmonic under Josef Stránský.
But they continued to make revisions to their version, amounting to thousands of changes, the last by Ottilie as late as 1961 (Rose having died in 1957).
The pianist Nathan Twining purchased a box of unidentified papers for $11, and it proved to contain the autograph score of Rose and Ottilie's version of Bruch's concerto, a work unknown to him.
[4][6] He and Martin Berkofsky then reconstructed Bruch's original version, and they recorded it for the first time in November 1973, with the London Symphony Orchestra under Antal Doráti.
