Interviewer: Although you're already 15 years around you didn't have many line-up changes, do always come along very well?
Niklas: Actually we do because we know each other for a long time four of the five original members are still in the band today and we grew up on the same street. We know each other since we are three or four. We began playing together without any previous experience, we all developed and learned together and I think that creates a band feeling, a band spirit that is much stronger than if you have a band with just professional musicians that are working together. It's important to us to have a good working atmosphere, because we write the songs with all band-members working and giving feedback, it would be impossible to have that if we weren't good friends and if we couldn't tolerate all the people's opinions. It's all very democratic, people are flexible and we have a good discussion, no big egos, no people getting pissed of, no making fights. It actually works surprisingly well!
