von Suppé, Franz (1819-1895)

Today the Austrian composer von Suppé is mainly known for his operettas and their ouvertures such as Dichter und Bauer and Boccacio, works which were successful in their time and have remained so. It is largely unknown that Suppé also composed sacred choral works: several masses, and his Requiem. Amongst these "serious" pieces the Requiem is the only one that is still being performed today.
