Walter Marchetti (1931 to 2015) spent the first half of his life, in his own words, "condemned" to bread-and-butter jobs: grape harvester, bricklayer, saddler, wine seller, metal shearer, turner, frame welder and an ample etcetera. In music he was self-taught; his attempts at serious study came to nothing, he said, because the establishment seemed to him a complete farce. In the early 1960s he moved to Spain and in 1964 founded the ZAJ group with his close friend and lifelong collaborator Juan Hidalgo, a Spanish cousin of Fluxus built on silence, walking, absurd actions and Cage's lessons.
