SINN was formed in 1998. Benoit (guitar) and Olivier (drums) got together with Jose (vocal) and Manu (bass) to start a new musical experiment. Immediately, the band began writing originals and soon were ready to record.SINN entered Time Studio in february 1999 and recorded 10 songs. The recording was released in limited quantities and mainly used just to get the name out. Soon after José and Manu decided to quit the band. Mario (BLACK BOMB A) joined the band for a while, before to be replaced by Plume (ex VAE VICTIS) then by Vinz (ex SYNOPSYS).

The band continued writing songs and playing a few shows until finally in November 2003, SINN, with Benoit on vocals, recorded the 6 songs mini cd « THE 666 X MURDER PROJECT ».

Some comparisons to bands like Grip Inc, Slayer, were brought up, but with undeniably original riffs, SINN carved their own path through the underground and established themselves as one of the best unsigned bands in France.

SINN are curently preparing to record their first full-lenght studio album which will showcase the bands talent even further.
