Both works on this program feature splendid and sublime sonorities. Into the Cello Concerto Elgar poured his most personal utterances and the sense of resignation that affects those in the autumn of their lives. The mournful, poignant tone of the cello seems to emphasize this quality, further heightened by the restraint with which Elgar uses the orchestra in this work, one of his most popular and one the greatest concertos in a cellist’s repertory. Artist-in-Residence Wen-Sinn Yang is giving his fourth concerto with the NSO this season. From Bruckner we hear one of his best-known symphonies, the Seventh, this awesome edifice in sound brings to many listeners’ minds images of vast spaces within towering cathedrals. A special breadth and grandeur infuse this music; time takes on new dimensions, and sumptuous sonorities are everywhere.
