Philipp and Eva met each other in 1981.
He thought: i wanna play football.
She thought: nothing. Because she was a newborn.
He was a six year old boy. They are brother and sister. In 2001, he already was a very good piano player and she had a good voice and ideas for music, they started to discuss. And they argued a lot. Like brothers and sisters do. After a few years, they found a sound, which they both like.
