This introspective but still intense work was composed by the modern Belgian composer and organist, Staf (Gustaaf) Nees (1901-1965), and is based upon the Gregorian chant, "O Filii", most usually sung on the Sunday after Easter, and dealing with the dramatic scene of the "doubting Thomas".
These five "modern Belgian" uploads are dedicated to Jonathan Orwig (giwro), who sent me these fine pieces! THANKS, J!
Jonathan will be the "Featured Uploader" in an article soon to be released on "The Barde", so be sure to check it out! :-)
