The world is changing, and Chelsea Wolfe's music is changing along with it.

The haunting California-based songstress has been known to weave elements of folk, metal and goth into her rich sound. But a shift in authorial perspective can be heard in her last two albums, 2017's thunderous "Hiss Spun" and the acoustic-based "Birth of Violence," due out Friday, Sept. 13.

“In the past, I was writing my songs in a very androgynous way, sort of between genders," said Wolfe." But (on) ‘Hiss Spun,’ my last album, and ‘Birth of Violence’ I was writing more so from the perspective of being a woman and navigating this world as a woman."

That's never clearer than on "Be All Things," a hymn to the depth of human complexities that stands as a central statement for the album and a reflection of changing modern ideas about gender norms.

"For me, ‘Be All Things’ was kind of this story of this woman in Victorian times who everyone looked at as this maiden but she actually feels more like a warrior inside. That kind of reflects my own life, I’m always trying to kind of balance the soft and the strong energies inside of me, and I think that definitely comes out in my music as well.

"And I think it is OK to balance those things and that’s kind of the way of the future, embracing the masculine and the feminine, or the soft and the strong, within you and expressing that.”

After years of expressing the strong side of herself in concert, backed by the mammoth sound of her live band, Wolfe is embracing the soft on her tour in support of "Be All Things."

An acoustic affair, the tour brings Wolfe to Union Transfer in Philadelphia for a Halloween engagement on Thursday, Oct. 31, followed by a Friday, Nov. 1, date at Brooklyn Steel in New York.

“Honestly, it’s a bit scary," Wolfe said of the tour. "I’ve been touring with my full band for so many years now that I’m used to having that sonic back-up, the wall of sound around me and behind me, so I’m really going to strip things back for this one. But it’s a good challenge to really take new and old songs and sort of strip them back and find new moods and new energy to bring to them. So I’m excited about it. I think it will be a really good growing experience for me as a musician.”

It was just a few years ago that Wolfe, around the time of "Hiss Spun," relocated from Los Angeles back to her native Northern California.

That move, she said, helped her get comfortable existing in her own skin and talking about her own story as she got older and, in her words, stepped into her own power.

"I’m 35 now and I think I’m just at a point where I’m reflecting a lot back on my own life and kind of taking stock and writing from that place, from my own experiences,” she said.

Take the "Birth of Violence" track "When Anger Turns to Honey" with this striking lyric: "Pain is the great connector."

“Strangely, it’s really easy to feel alone, especially in the era of social media," said Wolfe. "You constantly feel like you’re missing out on things or something’s wrong with your life and everyone else has their (stuff) together. But it’s really not true and we are really in this together.”

"When Anger Turns to Honey," Wolfe explained, is about trying to connect with "someone who isn't very kind to you."

"At the end of the end of the day, I can understand that someone who is really angry and acting out with insults and mean comments or whatever — this is just a small example, obviously — but those people are probably just in pain and something is going on in their own life that they’re not understanding or they’re not satisfied with," she said. "And that does connect us because I understand what that’s like as well. I’m not always satisfied with myself or own life either and I’m really hard on myself. I choose to deal with that by writing music and trying to transmute it into something positive.”
