With Litany, Estonian composer Arvo P¤rt created one of his most stirring works: a nearly 23-minute-long composition for orchestra and vocal ensemble based on the 24 prayers of St. John Chrysostom (one for each hour of the day). Commissioned for the 25th Oregon Bach Festival, the composition is both memorable and timeless. It finds influences in everything from chant to the repetition of modern minimalism. Play it loudly and the striking vocals of the Hilliard Ensemble simply soar against the strings of the Tallinn Chamber Orchestra. The orchestral Trisagion harkens toward Litany's mood swings and impact, but--sans voice--lacks the mysticism. One of P¤rt's best, and as sacred as modern compositions come. --Jason Verlinde
