"Tractus Perennis " is the sound performance by Paolo F. Bragaglia e Davide Mancini realized in collaboration with Fondazione Cassa di Risparmio, CIAC, Centro per la Cultura ed il Fondo Economico and Sistema Museo. The performance will develop in four cycles, lasting 40 minutes each, during the days of Saturday the 1st of July from 3pm to 9pm, at the former church of SS Trinità in Annunziata, where is exhibited since 2011 the artwork Calamita Cosmica, by the Italian artist Gino de Dominicis. Bragaglia and Mancini reinvent, through modular synths, the renaissance master’s creative process, unveiling new vibrations and harmonies with the subtractive synthesis.
