The Chorale presents two of the most iconic masterworks for choir and organ: Maurice Duruflé’s monumental Requiem, Op. 9, and Morten Lauridsen’s gorgeous Lux Aeterna. For the Requiem, which is based on Gregorian chant themes, the Chorale features vocal soloists and cello and organ accompaniment. Lux Aeterna, for choir and organ, premiered in Portland 20 years ago. Both works include renowned organist Dan Miller.
