What do an actress mired in scandal, a grieving political dissident, a previously enslaved African celebrity, and a court composer have in common? They’re all integral to the story of Messiah becoming a cornerstone of the musical repertoire. Heard now more often at Christmas, it was premiered at Easter in 1742 after three rapid weeks of writing by Handel, and it suggests, as author Charles King says, the staggering possibility that things might turn out all right. Charles joins Andy to reveal the characters in his book Every Valley, which in the American edition comes with the pleasing subtitle The Desperate Lives and Troubled Times That Made Handel’s Messiah.
