Luca Massaglia (http://www.lucamassaglia.com/) plays "Chant de Peine" ("Song of Sorrow") (no. 1 from "Neuf Pièces pour Grand Orgue") by Jean Langlais (1907-1991).
The "Neuf Pièces pour Grand-Orgue" were commissioned by the publisher, Bornemann. All the pieces were composed between 1942 and 1943, except the "Prélude sur une Antienne" (the eight piece of the collection), which was composed in 1929.
The "Chant de Peine" is inscribed "à la mémoire de mon cher Maître, Paul Dukas" ("to the memory of my dear teacher, Paul Dukas").
