Andrew Bird's records have grown quieter and more intimate in recent years, but he remains a remarkably dynamic live performer: Last year's Break It Yourself wouldn't seem to be the stuff of blockbuster live shows, and yet when he took it to the stage, he injected its characteristically smart, brooding songs with surprising intensity. Of course, it helps that, 12 albums into an unpredictable career, Bird has become a cult superstar whose fans clearly fuel him onstage.
