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 (with occasional small gigs). Mostly covers but one tune from the early days called "sport" is on the setlist (see facebook for examples).
