At midpoint in Messiah, Handel wrote three successive choruses that show not only his gifts as dramatist, but also test any chorus moving through this spacious oratorio. The Philadelphia Singers, in the first of their holiday performances Saturday, found in these sections the basis for some of the best singing of the evening.
David Hayes was leading the chamber choir and Concerto Soloists orchestra in a brisk and well-crafted reading, but when he began the second part, he and his singers moved up a level. They explored a dynamic range far greater than before, colored and shaded phrases in a way that heightened the dramatic message, and moved close to explaining why this music endures.
