December is the busiest month for the musicians of the LA Master Chorale. In addition to concerts chock full of carols, they’ve got multiple performances of Handel’s Messiah on tap this month—both the very popular sing-along version and what music director Grant Gershon jokingly calls the “please don’t sing-along” version. As Gershon tells KUSC’s Brian Lauritzen, this year, the LA Master Chorale is also celebrating the 25th anniversary of a piece of music that has been central to their repertoire ever since they premiered it 1994. Morten Lauridsen’s O Magnum Mysterium.
