He sang the title roles in Bernasconi’s Agelmondo (1760), Temistocle (1762) and Demofoonte (1766). Indeed in the role created for him Panzacchi moves very easily between fear and hope, and the role was so influential that it was imitated many times. From 1760 until he was pensioned in 1782, he was one of the highest-paid tenors in Europe.
He died in Bologna.
