A long time ago, I behaved pretty badly, which made me feel awful and so I wanted to write a song about it. I think it took such a long time to create the song—and the new album for that matter—because I’ve constantly been doing other things on the side: I have another band called Keøma, and was also playing guitar for Olli Schulz, along with other stuff too. So this song has just been with me for a while. But I did always know it would be the first song on the new album. I really like pop songs with darker lyrics. There’s a song “Walking On Broken Glass” by Annie Lennox that is a really happy pop song, but the lyrics are quite dark. She has this line “I’m living in an empty room / With all the windows smashed” and you think: Holy shit, that’s heavy! So for me, the thing I like about “Bad Behaviour” is that it actually sounds like a pop song, but the lyrics are quite aggressive.

MYP Magazine:

What makes this song so personal and so profound for you?

Kat (considers for a moment):

I mean every song of mine—even if it’s not about me—is obviously a little autobiographical. When you write music, you add your perspective, you add your ideas. And once you express an idea, you’re putting yourself into it, just because it’s you who’s making it. Sure, you can write stories about other people, but you also have to choose how you tell that story. And that’s where the connection with the artist comes in. But “Bad Behaviour” is just a classic “being-badly-behaved-in-a-relationship” kind of song.

MYP Magazine:

“Relationship” is a good keyword: The music video for “Bad Behaviour” shows different couples in a boxing ring, fighting each other with pillows. During the first seconds of the clip, we can see you playing the role of the referee. Are you explaining the rules of relationships—the rules of how to deal with each other?

Kat (laughs loud):

A little bit, yeah. I mean that’s the idea of the video. It’s a metaphor, obviously, for relationships: In relationships, it’s all fun and games until someone gets hurt. And yes, I guess I have more of a referee role in the video, trying to get the fighters to play fairly.
