Enfant mutant né de la collision entre les univers singuliers de Carl Roosens (du groupe Carl et les hommes-boîtes), du clavieriste/basse Christophe Rault et du duo bruxellois Zoft (qui compte le batteur de Wild Classical Music Ensemble (Born Bad), FACTEUR CHEVAL embarque l’auditeur dans un tourbillon rock ludique, intense et débridé.
