Green Day has been put on blast by Sex Pistols and Public Image Ltd frontman John Lydon, a.k.a. Johnny Rotten. In a new interview with the New York Times, the punk rock legend said it was “embarrassing” that bands inspired by Green Day are still wearing “spiky haircuts” and “trying to keep 1978 alive.”

Lydon elaborated, “How many bands are out there like Green Day now? I look at them, and I just have to laugh. They’re coat hangers, you know. A turgid version of something that doesn’t actually belong to them.” Lydon went on to call modern punk rock a “caricature” of itself and “a perfect backdrop to sell a pair of sneakers.”

Although Green Day started out as a punk act, the band has expanded its sound over the years into pop and even a rock musical. Frontman Billie Joe Armstrong told us a while back that it was important for Green Day to move forward artistically with each new album: “We always want to try to keep reinventing ourselves and come out with something new without changing our clothes. You know, not that we're trying to, like, have a new image or anything like that. I think we're just acting our age, trying to make something that's just the best record that we possibly can.”

Green Day teased fans in late August with posts on Instagram in which they indicated that they were rehearsing some of their early albums in full. The band has not offered any hints about what the practice sessions may have entailed. The band currently has nothing on its live schedule after completing the touring cycle for its 12th studio effort, 2016's Revolution Radio.
