It would be difficult to imagine a more powerful and moving piece than the Berlioz Requiem. The combined Eugene Concert Choir and Eugene Vocal Arts Ensemble will welcome guests the David York Ensemble of Portland to provide 180 talented voices raised in glorious song. They will be joined by tenor soloist Glenn Siebert and a symphonic orchestra assembled by the Oregon Mozart Players, featuring five incredible timpanists and four antiphonal brass choirs for the most ambitious project of the Choirs' 26-year history.
