Personally because i am from the younger generation of lion dancers i think with the participation of lion dancers themselves in hip hop culture and Lion dancing, there would be some overlap. That said, most of what I've seen with lions doing hip hop has been really bad.
I'm a b-boy and a locker as well as a lion dancer, that doesn't mean that i necessarily think the different dance styles should mix.
I've seen "lion hip hop dance" and i think it makes both b-boying and Lion dancing look half as good.
I think "cultureshock" was especially disrespectful/ horrible because why would they make a monk a female? why didn't they use an acolyte mask or at least the female masks, they exist.
The only overlap that i can see as being possible is Locking being combined with the monk dance because it's supposed to be goofy
http://www.youtube.com/watch?v=AGLpvwDtigw and has similar stance movements, monks walk with their feet out, same with locking and locking can use the props such as fan and bottle.
B-boying should not be used because the rhythm and placement is all off. Most of what B-boys do is on the ground with their hands so lions obviously cant do it and the monks just look weird.
Popping which is shown in the videos is also totally off when they try to do it with the monks. It looks weird because popping is supposed to make you look unnatural, using waves and all sorts of isolation.
Commercial hip hop doesn't really work either because its based upon the combination of B-boying locking and popping.
I just don't think that people really know what they are doing when they are combining the 4 dances, they probably don't know the background to the funk/ hip hop dances and their usage either.
