2008 release. NEOS has planned something special for Christmas 2008: a recently discovered Christmas Mass from the 15th Century. Rupert Huber, musical director of the WDR Rundfunkchor Cologne, was searching for a fitting programme for the 2007 Christmas concert. An acquaintance showed him an old book that her father had given her as a present. It turned out to be an antiphonal from the early 15th Century containing Gregorian chants. The pages are made of vellum, with music notation and text in a clear hand. It is also in fine condition and certainly from a Benedictine scriptorium. As if this were not enough: it contains an almost complete collection of the chants for Christmas Matins (liturgical chants of the hours, the Christmas Mass). It probably was written at the Benedictine Monastery of Gross Sankt Martin in Cologne, a church in which the Christmas Matins were first performed -- in modern times -- on 21st December 2007. Performed by: WDR Rundfunkchor Köln, Rupert Huber, (conductor), Benita Borbonus (soprano), Eva Budde (soprano), Carola Gunther (alto), Regine Röttger (alto), Markus Francke (tenor), Hein Heidbuchel (tenor), Guido Kaiser (bass), Harald Martini (bass), Pater Hermann-Josef Burbach (officiant).
