Only John Mellencamp, whose career began with a series of wrong turns, raw determination, and the audaciousness to demand he be taken seriously could create a box set as strange, representative, and labyrinthine as On the Rural Route 7609. In the era of the “track,” Mellencamp has issued a massive, beautifully packaged, and exhaustively annotated four-disc career retrospective that doesn’t lean on his hits (many aren’t here), but rather on more obscure album cuts, outtakes, rarities (17 selections make their debuts here), and more recent material – numerous selections come from 2007’s Freedom’s Road and 2008’s Life Love Death and Freedom. In Anthony DeCurtis' excellent liner essay/interview, Mellencamp claims he isn’t “trying to prove anything. . . it was a way for them to discover songs of mine that perhaps were overlooked because of the songs that were so popular on the radio.” Given his choice of material, he may not feel that his career-long demand has been met yet.
