He started to play the bass at the age of 15 and changed to guitar a year later. Therion in one form or another (known earlier as Blitzkrieg, Megatherion and other names) is the main band that has occupied him ever since he started playing, but he also made 3 albums with a weird psycho-metal band called Carbonized as well as some vocal performances in bands, such as the Swiss band Messiah and the Swedish band Liers In Wait. He has no formal music education and has never taken any kind of music lessions.
