The reason why many young people in the Vietnam War era were active was their lives were threatened by the draft and they were going to perhaps be forced to go overseas and fight in an immoral war.

Then about 12 years ago it dawned on me that folk music - the music of Woody Guthrie and Phil Ochs, early Bob Dylan, Johnny Cash, Pete Seeger - could be as heavy as anything that comes through a Marshall stack. The combination of three chords and the right lyrical couplet can be as heavy as anything in the Metallica catalogue.

In my own way, I was a rebellious kid.

My take is that there's two ways to approach history. You sit in your armchair and you watch it on the news and you return to your PlayStation. Or you get out in the streets and you make it. Like, when those Supreme Court justices, you know, legalize desegregation, it wasn't due to their infinite wisdom. It's because people whose names you do not read about in history books, people whose faces you will never see, were the ones who struggled and sacrificed, sometimes gave their lives, to make this country a more equal one. When, it's like those people don't make history, it's us.

Trump's ignorance in environmental science is a threat to the entire planet.

In our country there's never been a successful progressive struggle that did not have a soundtrack, whether it was the civil rights movement, workers' rights movement, women's rights movement. There's got to be songs at the barricades, and those are the kinds of songs that I try to write.

There are many fans of hard rock music that have been wrongly pigeonholed as apathetic. This music is not music for the elitist coffeehouse culture in SoHo. It' s rock 'n' roll music for kids across the land, and I think that makes it much more subversive in a way, in that it has the form and the function of a powerful, populist music, but it can carry very incendiary messages.
