Mozart's stunning and famously unfinished Requiem presents a musical bridge between life and death. Get ready for the Seattle Choral Company's alternately apocalyptic and angelic "Confutatis," which is one of the most intense passages of music ever written. The symphony is putting two other requiems on the program—Toru Takemitsu's Requiem for String Orchestra and Karl Amadeus Hartmann's Concerto funebre—giving the audience an opportunity to explore classical-era and contemporary interpretations of death. A natural choice for the middle of October, when Seattle shuffles off the last few rays of autumnal light and grows gloomier. by Rich Smith
