Livre du Saint-Sacrement (The Book of the Blessed Sacrament) is Messiaen’s last and longest organ work, a thematic cycle based on the sacrament of Communion comprising eighteen movements, many based on his recorded improvisations, arranged into three thematic groups. Hailed for his prodigious technique, vivid interpretive imagination and charismatic showmanship, Paul Jacobs is widely acknowledged for reinvigorating the American organ scene with a fresh performance style and ‘an unbridled joy of music-making’ (Baltimore Sun). He has performed the complete organ works of Olivier Messiaen in nine-hour marathons in eight American cities.
