The septet "Hobo Whistle" was created thanks to a collaboration between the Jazz School Jazz à Tours, the concert place le Petit faucheux  and Infingo at the occasion of the event "Tours Capital city of Jazz". The idea was to gather musicians of different generations in a common project, with Jean-Christophe Cholet as a conductor. This was a singular and enjoyable idea to observe how musicians react in front of artistic creation and improvisation, they be 20, 35 or 50. An opportunity for them to chose and assume their place as musicians and composers, in total respect with their convictions and artistic beliefs.
