Ernest Grosjean (1844 - 1936) published "Pièces pour orgue ou harmonium", a set of 56 pieces in two volumes, in 1902. The first volume contains 33 easy pieces, that can be played without the use of pedals. This Communion is a very nice, sweet flowing piece. Ideal to show of the softer stops of an organ.
The recording was done with the Hauptwerk software and the sampleset, made by Sonus Paradisi, of Casavant organ in the First Presbyterian Church of Bellevue, Washington
