I find this one fascinating, she combines pop-lock and bellydance and other hip-hop stuff. It's called tribal style bellydance. Slower paced than these other videos though, and it takes a few seconds to really get into it.
I usually don't fancy acrobatics in lindy hop so much because it is often there for showing off just because it is difficult, and I think it breaks the flow of the dance more than anything. In this clip though, it is done with such a great amount of humour and finesse so I'm totally charmed.
In my opinion, Max and Annie are now the second best lindy couple in the world. (After Skye and Frida.)
