Poligraf was originally formed in February 1998. After having lasted through many personnel changes, the band’s core finally dissolved in February 2003, right in the midst of the recording of a first album. Following a few months off, new collaborators were recruited and a new lineup finally gelled in June 2005. The boys found themselves in search of a bassist in March 2007 after the departure of Isaac Desgagné-Bouchard, and Denis Robitaille, one of the band’s founder, came back into the fold at the end of June 2007 to complete the present formation.

The band counts four members. Guitarist, keyboardist, and lead vocalist, Christopher Stewart also acts as main composer and operates the space where the poligrafic activities unfold. Member of the original Miriodor lineup in the ’80s, Denis Robitaille handles bass duties and vocal harmonies. Holding degrees in Music Education and Classical Interpretation, and full-time member of the Ensemble vent et percussion de Québec, Christian Lavoie fulfills both the roles of drummer and percussionist. Already known for his soundtrack to the short film « Falling, » Miguel Puerto cements the band with his confident guitar playing and occasional keyboard contributions.

Strongly influenced by progressive rock, the poligrafists draw from a wide range of genres going from world beat and jazz fusion, to symphonic music and free form improvisation.
