From the first beats, Bruce Springsteen's "Born to Run" is captivating. The lyrics, the imagery, the aspiration. In the day we sweat it out in the streets of a runaway American dream At night we ride through mansions of glory in suicide machines Tonight, Springsteen will perform in Boston. In honor of his visit, our production partner, WGBH Boston, is taking a closer look at "Born to Run" – and why it feels as relevant today as it did when it was penned nearly forty years ago.
