ON is the moniker for Sylvain Chauveau and Steven Hess abstract/minimal project. They improvise in a studio then hand to a guest musician to rework in whichever way they see fit.
Their first album, Your Naked Ghost Comes Back At Night was handled by dark-ambient master Deathprod, their second, Second Souffle by Brocoli favorite Pierre-Yves Macé, while their latest one, Something That Has Form And Something That Does Not was mixed by ambient star Christian Fennesz.
