At the beginning of the nineteenth century, Paganini and Giuliani both sought their fortune in Vienna, a city that later consecrated them as great virtuosos and founders of the Italian violin and guitar school. Paganini, AKA the "devil's violinist" was an uncanny idol and heartthrob to countless music lovers and also had a masterful command of the guitar. Giuliani was the premiere guitarist of his day and also had a great understanding of the violin. His nickname, "the Paganini of the guitar" helped intensify the bond between the two and further sealed their friendship and mutual esteem. Two world-class virtuosos, Rainer Kussmaul, on a Stradivarius from 1724, together with guitarist Sonja Prunnbauer, perform a selection of their great virtuosic duos.
