The painted face, the colored tunics, the experimental vocation and the overwhelming expressive energy: for fifty years the Osanna have embodied the purest and most flamboyant soul of prog, understood as a continuous overcoming of borders and crossroads of influences. Such is the sound of Osanna and such was the path of their founder Lino Vairetti. This book tells about his life and his art, from childhood in the streets of Naples to artistic adventures involving music, photography, performance, keeping the Osanna at the center, with their incessant name and formation mutations and with their inexhaustible research. which mixed classical music, jazz, Anglo-Saxon rock and a peculiar reinterpretation of the Neapolitan tradition. By crossing testimonies of the time with the memories and reflections of Vairetti, Franco Vassia sheds new light on creative processes and personal events, reconstructing creative ventures and different experiences, such as the soundtrack of the classic noir Milano caliber 9 by Fernando Di Leo or the tour with Genesis. Contains a selection of the band's lyrics chosen by Lino Vairetti.
