What's the hardest thing about being in a band with your sister?
We know each other so well that we get annoyed with each other easily, but the good thing about that is we feel very free to express it and get it out and not let it build up. It's hard because no one annoys me more than she does at times, and vice versa. But I don't love anyone more than her.

How do you guys split things up when it comes to the music?
Catherine doesn't play guitar. She doesn't play an instrument -- she just comes up with the melodies in her head. Sometimes if we're in the studio, we would occasionally collaborate, but generally we write on our own. And if I bring a song to Catherine, she'll put her vocal harmonies on it. Or maybe we'll decide, "This will be better if you sang it and I sang this part." We just figure out what's best for the song.
