Choral Arts Ensemble of Portland Opens 45th Concert Season with Elements Concerts. The music will explore the sacred, literary, literal and cultural associations of earth, water, fire and air through the music of Mozart, Weelkes, Haydn, Mendelssohn, Moses Hogan, Ola Gjeilo and others. Songs of earth explore its beauty, war-ravaged cry and relation to depictions of heaven. Songs of water juxtapose the calm of the sea with its fury. Songs of fire include music about volcanoes and judgment day. Songs of air include Beethoven’s Tempest sonata and music from The Creation. Performance repeats Sunday, Oct. 20th at 3 pm. Tickets: $10 to $18 available at Brown Paper Tickets.
