Festival Musica Sacra, Bever, België. Arvo Pärt based his 'Kanon Pokajanen' (from 'Canon of Repentance to Our Lord Jesus Christ', 1995-97) on the canon of repentance as handed down in the earliest Slavic-Christian manuscripts, dating back to the sixth century after Christ. The canon symbolizes the change, the transformation from day to night, the Old and New Testament, prophecy and the fulfillment, the here and now and the hereafter. This deals with the human and the divine, weakness and strength, suffering and redemption, mortality and immortality. In this broadcast, 'Kanon Pokajanen' is performed by the chamber choir Aquarius. This Flemish chamber choir is a trailblazer where new music and new concert formats are concerned. 'Kanon Pokajanen' is a great example of this: the singers are positioned in a circle in the center of a church. This dark church is only lit by candles and the music stand lights. After the choir has entered in procession, they sing for close to two hours. Performed by the Aquarius Choir led by Michael de Smet in 2008.
