In May 2018, Patton performed two concerts entitled "Forgotten Songs" in Modena, Italy, with the American pianist Uri Caine. The setlists of the concerts varied and included songs from Olivier Messiaen, Elton John, Slayer, Violeta Parra, George Gurdjieff, among many others. They also performed a new song called "Chansons D'amour" from an album Patton would later release with French musician Jean-Claude Vannier, "Corpse Flower" of September 2019. The shows were recorded, but it is not certain if the material will get a release.
