 Apparently, while in the USA, he recorded his voice on a Gianni Bettini cylinder which now appears to be lost.During the peak of his career, Campanini's main tenor rivals among his Italian and Italianate contemporaries were Roberto Stagno, Julián Gayarre, Angelo Masini, Francesco Tamagno, Fernando Valero and Francesco Marconi.Of these only Tamagno, Valero and Marconi have left gramophone records of their art.
