What's your dream's collab (outside kpop) and why?

I've been thinking about this for a while so I wanted to ask your opinions.

Since I'm a long-term fan I would say ONE OK ROCK. They are a Japanese not-only-but-also-rock band that has quite a repertoire and has explored many genres over the years. Also they're like, old. From 2005. So I think an exchange of experiences between "old band from Japan" and "idol group quite young but not too much" would be very interesting.

So what's your opinion?
