In 2002 Alessandro Bosetti travels across central Italy and Sardinia rediscovering the tradition of improvised poetry and especially focusing on « ottava rima » and « mottetto campidanese ». The outcome of these peregrinations full of meetings and recordings are a cycle of 5 – fifteen minutes long – radio documentaries for the Rai Radio 3 program « Centolire », further consolidated  in a half hour long documentary, which had been nominated for Prix Italia in 2003.
