What bands would you miss in an alternate reality?

We finally watched Yesterday, the movie about the Beatles never existing.

The things that never existed in his post-accident reality are the Beatles, Coca-Cola, Oasis, cigarettes and Harry Potter.

What are similar bands or consumer goods you think would cause large ramifications in our popular culture?

Or if you’re from another country, feel free to name your regional items.
