It’s likely that you either love the Mekons, or you haven’t heard of them at all. Formed as a punk band in Leeds in 1977, the sprawling lineup has remained more or less the same since the mid-'80s. Their sound spans multiple genres, among them American rock and roll and roots music. (They are, in fact, credited with producing the first alt-country album.) If you go to a Mekons show, expect to see some incredibly ardent fans, every music critic in town, and an energetic performance from all on stage.
