Loudon Wainwright III’s Years in the Making comprehends 45 years of off beaten tracks - over two hours of rare and unissued Loudoniana. It’s a 2-CD audiobiography, with orphaned album cuts, live recordings, radio appearances, home demos, and more. There’s audio snapshots of his early folk efforts, with Kate McGarrigle, George Gerdes, and Steve Goodman, singing traditional songs and covering Woody Guthrie and, of all people, Bob Dylan. There’s his 70s and 80s forays into the rock ’n’ roll world, including Leiber and Stoller’s “Smokey Joe’s Cafe” and his own “I Wanna Be on MTV.” There are featured appearances by Suzzy Roche, Bill Frisell, Van Dyke Parks, Chaim Tannenbaum, and David Mansfield, as well as by his sister Sloan, and all of his children, Rufus, Martha, Lucy, and Lexie.
