“Olivier Messiaen (1908-1992) is known for his unique composition style. Incorporating complex rhythms, harmony and melodies, Book of the Holy Sacrement for Organ is no exception to the composer's popular, distinctive style. Composed in 1984, Book of the Holy Sacrement is a major collection of Organ pieces by the composer. Messiaen began to compose the cycle of compositions in 1928 and it comprises 18 parts. The work was first performed in 1986 by organist, Almut Roessler, with a typical performance lasting about 100 minutes. Messiaen's Book of the Holy Sacrement is essential to all advanced, virtuoso and contemporary organists seeking to expand and vary their repertoire.”
