People who are offended about John Lydon’s apparent support for Donald Trump haven’t really been paying attention for the past 40 years. Regardless of the Public Image Ltd frontman’s actual beliefs about the United States’ current dictator-in-chief, it’s always been Lydon’s job to be a gadfly and provoke people. The fact that he’s defying the expectations of comfortably settled punk rockers is completely in character with the former Johnny Rotten who angered supposedly liberal classic rockers in the late 1970s with his dour observations about how many of the hippies ended up just as conservative as their parents. What should be more troubling to listeners is how the always forward-thinking PiL seem to have settled into atypical sentimentality with a new career-spanning box set and a de rigueur nostalgic documentary. But Lydon, guitarist Lu Edmonds (Mekons, The Damned) and drummer Bruce Smith (The Pop Group) still make these deathly disco chants sound baleful and menacing.
