Sébastien Groulx, originally from the Gatineau region, began guitar lessons at the age of ten. From the age of fifteen to 25, he studied classical guitar with Patrick Roux. At the age of seventeen, he began teaching guitar privately. He became a member of the group Intersection, with whom he played on Parliament Hill as part of the Canada Day celebrations.

While studying classical guitar, he won the Scott Bursary, enabling him to perform at Place des Arts.

From 1996 to 2005, he was a founding member, guitarist, composer, arranger and musical director of the Théodore Fontaine group. With this group, he obtained a record contract with Mille-pattes productions (Bottine Souriante) and co-produced their album with Hugo Perreault (Okoumé, Richard Séguin). The group played a number of major venues in Quebec and Ontario, and appeared several times on Radio-Canada television.

In 1994, Sébastien perfected his jazz interpretation skills at CÉGEP St-Laurent, then went on to earn a Bachelor’s degree in music education at UQAM.

For several years now, he has been teaching guitar and ukulele at primary school level for the Laval school board, and working on a solo career as singer-songwriter and arranger for the group SIG ATOM.
