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. Obstipation started again in 2016 and together with a third band member (Gareth) they play "unplugged" music and rehearse on a regular basis (with occasional small gigs). Mostly covers but one tune from the early days called "sport" is on the setlist (see facebook for examples).
