The election of Donald Trump had an effect on the lyrics found on Foo Fighters’ upcoming album, Concrete and Gold. In a new interview, frontman Dave Grohl said that current events have caused him to think about the type of world his daughters will inherit, which wound up in the new songs.

"I look at all of the different periods of time where I've written lyrics, and they all have their own references and different phases," Grohl told Kerrang! (via Blabbermouth). "This one came out pretty clear: I'm a father now, I have to consider a lot more than I used to, and I think I've realized we're not all as free as we were before. In every way. I mean, as the political arena started heating up in America before the elections, it became clear that there was so much more threatening all of our lives than I'd considered before."

For Grohl, it’s a trio of areas where he disagrees with Trump — the environment, women’s rights and international diplomacy — that were hotly debated during last year's electoral season. "I'm looking at a candidate that has blatant disregard for the future environmentally, when it comes to women's rights, diplomatically,” he said. “I have three daughters that are going to survive me for decades — how are they going to get on unless there's some positive and progressive change?"

In the track "Run" Grohl sings, "The rats are on parade / Another mad charade" and in "The Sky is a Neighborhood" he says, "Mind is a battlefield, all hope is gone, trouble to the right and left" while "Arrows" features the lines, "She had arrows in her eyes, fear where her heart should be, war in her mind."

He previously explained that the theme of Concrete and Gold was “hope and desperation,” adding, “Some of it is a little political.” But he also pointed out that the title song, which comes at the end of the LP, featuring an uplifting message: “I have an engine made of gold / Something so beautiful / The world will never know / Our roots are stronger than you know / Up through the concrete we will grow.”

Grohl reflected in the new interview, "It's weird – it really sparked a lot of my early, alienated, freakish punk rock feelings from when I was a teenager. I was one of those little freaks in his blue bedroom in the middle of a really conservative part of Virginia feeling like I was just an alien. I started feeling that way again."

Foo Fighters' ninth album is released Sept. 15, ahead of a U.S. tour that starts next month. The record features a guest appearance by someone Grohl described as "probably the biggest pop star in the world." Guests who have been confirmed include Paul McCartney and Alison Mosshart of the Kills.
