Ztfs has born as a radical improvvisation combo, founded by Michele Maglio, that leaved the project to create Logan and his Psychotica records. The remaining members of the ensemble, often changed in time because of the open borders of the project, record this demo in 2003 with Edoardo Troilo on guitar, Attilio Muolo on drums and Mimmo Chiffi on bass, playing tracks with a precise structure but anyway with a freeform style on stage.
