Mekons concerts are dancing-in-the-face-of-the-apocalypse parties, and at their center is Sally Timms. Her beautiful, pure voice is way better than what you’d expect from a post-punk, country-tinged, what-have-you band, and, as she explains here, she feels duty-bound to spread joy from the stage, especially when times are dark. Typically quick-witted and thoughtful, she discusses the Mekons’ early days in Leeds, England, and their unique, enduring creative process; her longtime friendship with the late Pete Shelley of the Buzzcocks; how she and fellow Mekon Jon Langford have embedded themselves in Chicago life; and why she has helped so many strangers get vaccinated.
