Jem started out his career as an engineer for Olaf Opal. In that time, Jem, who comes from the Rheinland area of Germany, worked on ‘Narcotic’ from Liquido, Reamonn’s ‘Josephine’ and also with cult bands such as Miles. Ultimately Jem was also involved in Tobias Kuhns’ Miles follow-up project ‘Monta’ and had an distinctive influence on albums from Madsen and Virginia Jetzt!, Klee or Martin&James. Jem is especially in demand as a mix engineer and has made a name for himself in the rock scene (Guano Apes, Such a Surge, Donots, Haudegen), as well as in the pop scene (Juli, Sascha). In cooperation with Andreas Herbig Jem produced national acts such as Udo Lindenberg (3 albums), Ich+Ich and Nena. He also worked on the debutalbum of Andreas Bourani and Royseven. His latest works are productions for Luis Laserpower or the mix of Christian Steiffen and Christina Stürmers new album „Ich hör auf mein Herz“.
