In 1981 Gerhard and his friend Mikael played in a punk band called Obstipation. After that he went into heavy metal and then big band student music and jazz. Then he had a long pause from music. Now Obstipation exist again and together with a third band member (Gareth) they play "unplugged" music and rehearse every weekend. Mostly covers but one tune from the early days called "sport" is on the setlist.
