The original choral setting of O Magnum Mysterium, premiered by the Los Angeles Master Chorale conducted by Paul Salamunovich in December, 1994, has since been performed thousands of times throughout the world and was also designated as an American Choral Masterpiece by the National Endowment for the Arts. The genesis of this motet is discussed in my Wall Street Journal article. “Zurbaran's 'Still-life with Lemons, Oranges and a Rose.'”
