There are a bunch of professionals / models in it.

(The people on instruments = professionals at playing their instruments, I guess, and the models are actual models that work in the industry.)

As for the outfits, a lot of them have been worn by GaGa, or at least she has also worn stuff from the same collections. But this is mostly because both Ayu and GaGa chose to use the best British designers when choosing fashion designers... it's more that Ayu and GaGa probably have similar tastes in avant garde fashion and that's why things kind of seem strange.

I think this is Ayu's first time venturing into the world of "fashion" in a PV, haha. (wearing designer outfits and etc. anyway)
