Jeff Tweedy is best known as the front man of Wilco, the rock band he formed in Chicago in 1994. In recent years, he’s been working more often as a solo artist, putting out records under his own name as well as a memoir and essays on songwriting. Amanda Petrusich sat down with the singer-songwriter to talk about “Twilight Override,” which comes out later this month. Recorded with Tweedy’s two sons and a number of his fellow Chicago-based musicians, “Twilight Override” is a triple album of songs centered on themes of time, aging, fear, and “making peace with something ending.” “If we're looking at the word override, what am I overriding?” Tweedy says. “I mean, twilight's beautiful . . . but you need to override your fear of it.” Tweedy performs acoustic versions of “Love Is for Love,” “Lou Reed Was My Babysitter,” and “Forever Never Ends.”
