WHAT: The Los Angeles Master Chorale will light up this holiday season with four spectacular concerts that include a world premiere by Swan Family Artist-in-Residence Eric Whitacre, the now-classic O Magnum Mysterium by Morten Lauridsen, and Handel's Messiah. Eric Whitacre will conduct the venerable ensemble at Festival of Carols on December 7 at 8:00 PM and December 14 at 2:00 PM at Walt Disney Concert Hall, including his world premiere of The Gift of the Magi, a setting of O. Henry's charming tale of love and generosity.
