Love This Giant developed like many a New York City-bred friendship. Both parties are kind of hazy about how it began, but after a couple of semi-chance encounters, David Byrne and Annie Clark, who records and performs as St. Vincent, embarked upon a creative dialogue that has flourished over the last three years. Curious, mutually appreciative acquaintances became determined co-conspirators, and the result is an album that’s brash and, quite literally, brassy. Byrne and Clark spin their intriguingly enigmatic tales, by turns whimsical and dark, backed by a large brass band in lieu of a traditional rock lineup. There is a magical urbanity to Love This Giant: It’s as if they’re dancing in the streets, their voices soaring over the rhythms, the melodies, the barely contained cacophony of the city.
