Are there any studios in the U.S. that teach capoeira? Is capoeira kinda like krumping?

I would try googling places for around where you live. I just tried a sample one with "Capoeira _______" with the blank being the name of the city (or state).

And I don't actually do capoeira, so I'll leave the explanation to someone else--Although, I'm under the impression that its like martial arts + dance
