Following his classical music studies at the Conservatoire of music in Le Mans, Jean Louis Pommier dedicated himself to jazz and has played in many French metropolitan jazz formations (Big Band Jean-Loup Longnon, Big Band Ornicar, Bande à Badault, ONJ Badault, Barthélemy & Tortiller, Onztet de Caratini, Multicolor Feeling d’Eddy Louiss, Zoom Top Orchestra, Le Gros Cube d’Alban Darche...)
In addition to his many musical collaborations he participates in numerous teaching projects. He has also emerged as a renowned composer completing commissions for Radio France and Europa Jazz Festival. He composes particularly for his group Qüntet and more recently for the LPT.3 trio.
He is also a co-founder (along with Alban Darche and Sébastien Boisseau) of the very active music label and collective YOLK which has offered a generation of musicians the opportunity to flourish.
