Hey, I am looking for any info from anyone who has any insight on this prison style fighting system called 52 blocks or Jail house rock/Jail house boxing.

I hear its really a devestating way of fighting. Somewhat familiar to capoeria and silat hybrid.

Any insight would be greatful thanks

There's a book that has a little bit of it--something like Martial Arts from Around the World. I've seen it in bookstores.

check out stickgrappler's site.

52HB/Jailhouse rock/boxing is one of the many many links at the bottom of the page (I'm putting you on the main page so you can see the scope of the site - incredible). It's probably as complete a look as you'll get, includes pics of moves, etc.
