Wednesday night, Kevin Gordon introduced the final song of his set (not counting the obligatory encore, of course), with a warning of sorts. It was, he said, a song that had its origins in the Louisiana where he grew up, a story from his youth (he was 13 at the time), and it was long — “a long song but a short movie,” as he jokingly put it.

What followed was “Colfax/Step In Time,” from his latest record, “Gloryland,” one of the most remarkable of the many remarkable songs that Gordon has written. It’s a story-song that manages to combine a self-deprecating look back at the juvenile delinquency, raging hormones, and other foibles of the high school male with the sudden entrance of a racial situation that vibrates with danger. And it was, no joke, of cinematic proportions.
