Schematically, we have an electric guitar player, a classical music double-bass player and a jazz drummer, all dreaming of an on-the-spot concert, with perfectly controled swerves, confronting their own cultures, and generating the unexpected. Under the stratus: nebulosity, turbulences and wintry weatherabove: light, energy and a liking for risks. The musical cultures of Christian GRAF, Pierre-François MASSY and Marcel PAPAUX, once they've sojourned in the cauldron of their compositions and improvisations, mirror the meteo paradox that the three musicians chose as an emblem: hot and cold, shade and light, smooth and harsh, in other words a quilt and a snow-blower.
