Olivier founds the band in May 2011 with Audrey Adornato.
Previously in 1995, he joins Crematorium (Melodic Death Metal) for a period of three years. After a break of several years he composes for Timecode Production soundtracks for their short films. He plays ultimately for the band Evershade in 2009, where he meets some of the current members of Fourth Circle.
Strongly inspired by movie music and classical music, Olivier puts a point of honor to provide symphonic arrangements which characterize songs of Fourth Circle.
