Extreme Sport in Central Park
Well I was originally going to write these people I saw in Central Park off as crazed yogi Hari Krishna hippie cultists but upon further investigation it turns out they are participating in an interesting martial arts sport called capoeira. Capoeira Angola (the derivation seen below) seems to be like slow motion karate timed to music emphasizing technique and strategy over speed and force. Very interesting. Almost reminds me of that scene from Roadhouse where Patrick Swayze practices outside the barn by himself in a zenlike trance while the "I'm upping my skill level for the big climax" montage music plays.
Note the 4 stages of Michael Jackson represented; (l to r) future, '60's, current, 70's.
