In Forest Park, Queens, N.Y., an old relic suits Steve Gunn's sound. The Long Island Railroad's Rockaway Beach Branch used to run through the park. It's been abandoned for over a half-century, and trees have grown between the ties, skewing the rails and jarring the lines. Late this past summer, Gunn stood on the tracks of this worn American symbol and sang three songs off his latest album — songs about meandering, home and the crooked paths that take us wherever we're meant to be.
