David Byrne and St. Vincent a dynamic duo at Orpheum
Minutes before Sunday’s concert began, when the Orpheum stage was littered with brass instruments lying on the floor but devoid of people, David Byrne made an announcement from backstage: Picture-taking was encouraged. So was audio/video recording. But what he encouraged most of all was simply enjoying the experience and capturing it in memory. A necessary invitation? Hardly. The former Talking Head’s performance alongside St. Vincent (also known as erstwhile Berklee student Annie Clark) consisted of one jaw-dropping moment after another.
