Tamtrum was an Aggrotech duo from Aix-en-Provence (France), composed of artists Benoit XVI and Sylvicious. They released many singles on many different compilation albums such as Cyberlab Volume 5.0. The friendship of Benoit and Sylvicious started in a French black metal band called Mandragor. When this band broke up, Sylvicious continued with his band Lucky Striker 201 until he met Benoit, who had already composed a couple of songs which would later be included on Some Atomik Songz. They sent demos out to multiple labels until the French label La Chambre Froide picked up the band. The resulting release after Some Atomik Songz would Versus (2004) - a split CD featuring Lok-8 as well.

The band has become well known thanks to their live shows which are more than just mere concerts. Sonic manipulations are accompanied by fire breathing and other uncanny acts you would rather expect to see at a carnival than a concert. By touring Europe extensively they made a name for themselves due to their harsh, grinding elektro which manages to mix the genre in its essence and the atmospheres of black metal. In 2005 they released the mega hit Le Son de la Pluie (The Sound of the Rain) on the Alfa Matrix compilation Endzeit Bunkertracks: Act I. It became number one on the DAC.
