Twenty-five years ago, an unsigned band out of Athens, Georgia, named Drive-By Truckers recorded the equivalent of a tree falling in the forest with no one there to hear it. A very big tree. It was a thematic, double-album colossus loosely about, as one of its signature songs put it, “the duality of the Southern thing,” and it was accomplished exclusively between the hours of 6 p.m. to 6 a.m. due to the sweltering conditions in their makeshift studio in a second-floor uniform shop.
