Which person from "JoJo's Bizarre Adventure" does NOT house a reference to a band, artist, or song earlier than 1980?

The answer is Giorno Giovanna. Throughout JoJo's Bizarre Adventure, the majority of characters' names and abilities are directly inspired by bands, artists, or songs from earlier than 1980. However, Giorno Giovanna, the protagonist of Part 5: Vento Aureo, does not have a name or ability referencing any band, artist, or song prior to 1980. This is because his character and story arc were created by Araki Hirohiko after 1980, making Giorno an exception in terms of his lack of musical references.
