Ole Christian Öhman (born 13 October 1973),[1] also known as Bone W. Machine, is a Swedish drummer, best known as a member of Dissection from 1990 to 1995 and Deathstars from 2000 to 2011.
Öhman joined Dissection in 1990 and played drums on the band's 1993 debut album The Somberlain.
In 2008, it was announced that Öhman would not partake in Deathstars' European spring tour with Korn for personal reasons.
In October of that same year, it was announced that Öhman had been diagnosed with a severe case of tennis elbow in his left arm and was forced to leave Deathstars' ongoing tour.
[3] A show in Frankfurt had to be shortened after the drummer had performed for 45 minutes in severe pain and long-time friend of the band Oscar Leander was subsequently brought in as a touring replacement.
