“The Source” is the next step in Allen’s musical and spiritual voyage, and a further exploration of his early jazz influences. To share writing tasks and take care of the arrangements, he called on saxophonist Yann Jankielewicz, with whom he has worked since 2009 and the album Secret Agent. They began by getting together to listen to and exchange their favorite jazz records: Lester Bowie, Charles Mingus, Art Blakey, Gil Evans… albums that served as a compass to guide them on their way.
