With the centenary of Olivier Messiaen drawing nigh, here are some additions to my Messiaen 100 post of some weeks back. First, the DG label is releasing a mammoth, thirty-two-CD Complete Edition of the Maître's works, with authoritative performances by the likes of Olivier Latry, Roger Muraro, Pierre Boulez, Myung-Whun Chung, and Kent Nagano (his great recording of Saint François d'Assise). Also, I earlier neglected to mention that the Cleveland Museum of Art is offering a strong cluster of events over the next several weeks: the Quartet for the End of Time twice, Christopher Taylor playing Vingt Regards on the night of the birthday (Dec. 10), and From the Canyons to the Stars with Oberlin players on Dec. 13. Note also ongoing observances at Jacaranda in LA; Mark Robson will do the Vingt Regards on Dec. 6. Matthew Odell plays the same huge work at An Die Musik in Baltimore on Dec. 7. Up in New Haven there's a series called Messiaen at Yale, with Paul Jacobs undertaking Livre du Saint Sacrament, the composer's final organ masterpiece, on the 10th. Here in NYC we'll have a Quartet in the Music at Our Saviour's Atonement series in Washington Heights on Dec. 7; the same work at NYU's Mission Française on Dec. 10; a Voices of Ascension concert the same night at the Church of the Ascension in the Village, with yet another Quartet and Jon Gillock playing organ selections; a Miller Theatre tribute with AXIOM on Dec. 13; and Reinbert de Leeuw conducting the Turangalîla with Yale players at Carnegie on Dec. 14 ($10-25). But nothing on this continent beats the climax of Automne Messiaen in Montreal: the entire organ output during the day of Dec. 10, plus Vingt Regards that night and a Nagano-directed Saint Francis on birthday eve. See the master event list for Messiaen events around the world. The day after, of course, Elliott Carter turns one hundred; James Levine leads the celebration at Carnegie, with a Making Music event the following night. At Southbank in London, the unstoppable Boulez will lead a Messiaen concert on Dec. 10 and a Carter concert on Dec. 11, including something of his own on each night for the sake of variety — or, perhaps, continuity.
