In page Sergei Rachmaninoff:

"

From 1919 he made 35 piano rolls (12 of which were his own compositions), for the American Piano Company (Ampico)'s reproducing piano. According to the Ampico publicity department, he initially disbelieved that a roll of punched paper could provide an accurate record, so he was invited to listen to a proof copy of his first recording. After the performance, he was quoted as saying "Gentlemen—I, Sergei Rachmaninoff, have just heard myself play!" For demonstration purposes, he recorded the solo part of his Second Piano Concerto for Ampico, though only the second movement was used publicly and has survived. He continued to record until around 1929, though his last roll, the Chopin Scherzo in B-flat minor, was not published until October 1933.[4]
