When Wilco frontman Jeff Tweedy was a young punk growing up in Belleville, Illinois, he felt sure about what sort of music he did and didn’t like: “We thought that hippies were the enemies,” he says now. “I don’t know where we got that idea.” In an interview with Jancee Dunn recorded in April, Tweedy explains how a fresh appraisal of his own musical tastes changed his palate and why he thinks the idea of a generation gap was destructive to young musicians growing up in the ’70s and ’80s.
