with its highly lauded recordings of the music of Arvo Pärt, will perform in the intimate confines of the Cathedral of the Immaculate Conception. The program will feature two pieces by Pärt, the Kanon Pokajanen and the Te Deum, as well as two works by Johann Sebastian Bach. The juxtaposition of Bach's classic choral works with Pärt's intriguing faux-medievalism should make for a fascinating performance. Pärt's music, particularly in its recordings by the Estonian Philharmonic Chamber Choir, has been responsible for the current vogue of chant and polyphony on the classical music stage. This performance seems certain to be a gratifying, mystical experience.
