I'm really curious about the process behind creating relay dances, how much is choreographed vs improvised, how many takes they tend to do before getting to a version they're happy with, stuff like that.
Would be neat to see a relay dance making-of film.
When kiddo first showed me kpop relay dances (about 5 years ago?) they seemed a lot simpler & less compelling than they are now.
Kiddo says it's like any other art form, it matures over time.
