“Charge,” the first song of Elbow’s concert, is aptly titled. The British band storms the audience with startling vigor, urged on by Richard Jupp kicking his bass drum with the force of a Clydesdale. Midway through the new track, a pair of female violinists seated at the rear of the stage swoop in. Their dramatic musical squall increases the barometric pressure inside the room. The audience somehow finds its breath for a loud cheer.
