Angelo Sasso is a heavy metal drummer credited for playing the drums on two Running Wild albums, Victory and The Brotherhood. It was suspected that a drum computer was used in recording these two albums and that "Angelo Sasso" is simply a fictional person used to cover this up. This was denied by Running Wild's guitarist Rolf Kasparek, who claimed that "Angelo Sasso" is actually a pseudonym of a friend of his, who didn't want to be credited under his real name[1].
In either case, "Angelo Sasso" became a running joke in the German metal community, with other bands crediting their drums to "Angelo Sasso"[2][3] where drum computers were used.
