Denis Gancel has a classical musician training, he conducts orchestra at the age of 18 and joins the Ecole Normale de Musique in Paris in the piano class of Jeannine Bonjean. He meets Jacques Loussier in 1985 who becomes his friend and mentor. Jacqus Loussier invites Denis Gancel to chart his own musical route.

The first step is the creation in 1993 of ‘Bonsoir Paris Jazz’, a jazz band where he meets Nicolas Chelly and Philippe Nadaud, and discovers jazz classics.

The second stage is crossed in the 2000s with the writing of the first original compositions. It is from these compositions that Denis Gancel proposes in 2015 to Nicolas Chelly and Philippe Nadaud to create the quartet. The Denis Gancel Quartet records its first album Miscellannées with Yasmin Shah as a guest in 2017.

The quartet regularly performs in several festivals in France.

Bric à Brac launched in 2019 marks a new stage on the musical career of Denis Gancel Quartet with Philippe Nadaud (Tenor Sax & Flugethorn), Nicolas Chelly (Double Bass), Hidéhiko Kan (Drums), and Yasmin Shah (vocals) and Jacques Berecochea (trumpet) as guests.
