Black Flag was everything but a conventional hardcore band. Henry Rollins had terrifying energy about him that caused a rift between him and other bands of that era. Outside of the stage, he was a lovable, goofy jock who cared deeply about ethics and politics. He had ongoing competitions with Iggy Pop, Bad Brains, Circle Jerks, and even traditional hardcore bands like Cro Mags and Madball in the 1990s. Currently, Rollins works as an activist and advocate for sober culture, although he has always preached the necessity of staying true to oneself, through sobriety, artistry, and any other means necessary.
Gwen Stefani
Gwen Stefani didn't care about the way the public perceived her when she started No Doubt in the early 1990s. Her punk posture, demeanor, and credo held true through her career, all the way until now since she has had a significant tonal shift.
Although Stefani has navigated her career over to the pop side of things, her reggae-inspired punk band is still one of the highest coveted groups in the history of punk music. Stefani introduced an entire generation of women to the punk movement, signaling that you don't have to censor yourself, and you can stay cool while doing it too. Even in her current vane of music, Stefani holds true to her "I don't care" personality that people either totally love or completely hate. She is a beast on stage, her audience interaction is one of the best, and getting to see No Doubt live when they were playing was a privilege that not many people can say they had.
Billie Joe Armstrong
Critics have a lot to say about Green Day and the "only time they were good," however, those people probably never saw Green Day in their later years.
