The New York Philharmonic performed Max Bruch's Concerto for Two Pianos only once in 1917, but the composer might not have recognized it, had he been in attendance. The late-Romantic German composer, whose limited fame rests largely on his more widely performed Violin Concerto No. 1 in G Minor, had entrusted the work to the Sutro sisters, Rose and Ottilie. But they edited it heavily for their two performances of the piece (the other with Stokowski in Philadelphia), even jettisoning a movement, and copyrighted it for themselves. Apparently they went on to scam Bruch out of the profits of that Violin Concerto, too.
