Mozart was working his Requiem on his deathbed in 1791, leaving it for protégés to complete. A masterpiece of the choral repertoire, the work is “an unlikely but unforgettable alloy of ecclesiastical grandeur, Baroque fugue and the subtlest mood painting,” wrote a Portland Phoenix reviewer in 2001.

“Known for operatic music that can convey scene or character with a handful of notes, Mozart used that skill here to portray a believer facing death: feeling dread at the end of this life, anxiety at the prospect of judgment, abject yearning for forgiveness.”

The choir will be accompanied by an orchestra consisting of students and community members.

Described by a Village Voice reviewer as “one of those special singers whose technique and blooming sound always serve sense and emotion,” world-renowned soprano Lisa Saffer sings at ÀÖ²¥´«Ã½ College at 7:30 p.m. Friday, May 8, in the Olin Arts Center Concert Hall, 75 Russell St.

Joining is pianist Anastasia Antonacos, an award-winning musician with a worldwide following. Admission is $10 for the general public and $4 for students and seniors. For tickets, visit . For more information, please contact 207-786-6135 or olinarts@bates.edu.
