Luca Massaglia (http://www.lucamassaglia.com/) plays "Berceuse sur deux notes qui cornent", JA 7 bis, by Jehan Alain (1911-1940).
The piece was written in August 1929, and it's based on two notes of the composer's home organ that had stuck, producing what organists call a cipher. That organ was built by Jehan Alain's father, Albert, and was moved in 1991 from the Alain family's home in Saint-Germain-en-Laye to the Grange de la Dîme in Romainmôtier (Switzerland), where the "Jehan Alain" Association is based.
