DisasterTheory's Mark Thomas Gets Personal On New Single “KALLIE ANN”

PITTSBURGH, PA — DisasterTheory, Pittsburgh’s rising metalcore force, is releasing one of their most emotionally charged tracks to date — “Kallie Ann”, out everywhere Monday, May 26, 2025 and it takes on a very different sound for the guys.

Frontman Mark Thomas peels back every layer with this new single, offering fans a vulnerable look inside a complicated and deeply personal chapter of his life.

Though most of the fanbase has responded with overwhelming support, the song has also stirred some conversation. Some have voiced discomfort or confusion over the song’s meaning. Thomas isn’t hiding from it — in fact, he’s standing behind it fully.

“Some people are upset about the release, and that’s okay,” Thomas says. “But this is who I am. I write from the heart, and I always will. ‘Kallie Ann’ isn’t meant to hurt — it’s a love letter, not a dagger. It’s not a negative song. It’s honest. And sometimes honesty is messy.”

Q&A WITH MARK THOMAS

Q: So… who is Kallie Ann?
Mark Thomas:
Kallie Ann is the name behind an on-and-off relationship that’s meant everything to me. It’s about a woman I’ve loved through chaos, miscommunication, distance, and pullbacks. We've never had a lot of stability, but the connection was real — is real. This song isn’t about blame. It’s about holding onto something you believe in, even when the world tells you to let go.


Q: The lyrics feel stripped down emotionally — like there’s no armor.
Mark:
Exactly. I didn’t want to hide behind metaphors or distortion this time. I’ve written songs full of fire, rage, and fight — but this one? This one’s just my heart bleeding on a page. I recorded the vocals in a single take. I didn’t want to polish the pain. I wanted it to hurt me, and I wanted that hurt to be real.

Q: Was the reaction what you expected?
Mark:
Honestly? No. I expected emotion, but not controversy. Still, I don’t regret it. Music isn’t always meant to make people comfortable. It’s meant to make people feel. This song might not be everyone’s favorite, but it’s probably the truest thing I’ve ever written. I think anyone that may have an issue with it, is likely due to them not facing some things they personally feel.


Q: There seems to have been confusion about whether the song was even going to be released. Can you touch on that?

Mark: I don't know where that confusion would come from. I have never said publicly or privately to anyone that the song would not be released.

Q: What would you say to those that have a problem with the song being released?

Mark: Nothing really. I would only imagine that the people who have a problem, are either those that didn't go through it or those that caused the problem the song refers to. So I'm okay with them having a problem.

Q: What would you say to her if she hears it?
Mark:
I’d say… I meant every word. I always loved you, even when I apparently couldn’t say for show it right. Even when you pushed me away, you were never far from my mind. This song is my screaming you name into a void and my reminder that you mattered. You still do.

“Kallie Ann” will be available on all major streaming platforms starting May 26, 2025. A stripped-down acoustic version will be released alongside a black-and-white animated music video — featuring red as the only color to symbolize passion, pain, and the unresolved threads of love.
