In 1998, Björn was exposed to real hard slamming techno, broadcasted by the Cologne radio station Evosonic Radio. After soaking in radio shows like "Areacode" and "Subsonic" he started to create his own kind of techno and in 2001 got in contact with acid legend Rob Acid of Junkfood Records. Only one month later he released his first EP on Junkfood (JF035 - Mark 12 EP) under the artistname B.Bommersheim. Since then, Björn has gone on to release records with numerous labels and has established himself in Germany and the entire techno world as a force to be reckoned with.
He performed Live Acts as "Midisports" (together with Marius Keller).
